Fluid Mechanics

The Vane Pump (Product Code: SLE/EFM/01) is a fixed displacement, balanced vane pump that delivers a set volume of oil for every full turn of its shaft. It is built for use with the Positive Displacement Pump Module, where students run it for experiments, demonstrations and project work on hydraulic machines. Produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it belongs to our engineering lab equipment for India’s polytechnics, engineering colleges and technical training centres.

Specifications

Typical Use

Once the pump is mounted on the Positive Displacement Pump Module and coupled to the Universal Dynamometer, students can vary shaft speed and delivery pressure and record how flow, torque and power respond. Because a positive displacement pump moves a fixed volume per revolution, the class can compare the theoretical flow with the measured flow to find volumetric efficiency, and see how internal leakage grows as pressure rises. In a balanced vane design, opposing pressure zones inside the housing help even out the side loads on the rotor, a point worth discussing when comparing it with other pump types.

Among lab equipment for technical institutes, interchangeable pumps like this one let a single test module cover several machines in one term. The self-sealing connections keep oil where it belongs during changeovers, so students can remove and fit the pump without draining the circuit. Wipe connections before fitting, keep the oil clean, and follow the direction of rotation set by the dynamometer.

The Gear Pump (Product Code: SLE/EFM/02) is a positive displacement pump in which a pair of meshing gears carries a fixed volume of oil from inlet to outlet on every full rotation of the shaft. Designed to fit the Positive Displacement Pump Module, it gives students a hands-on way to study one of the simplest and most widely used hydraulic pump designs through experiments, demonstrations and projects. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, an engineering lab equipment manufacturer serving technical colleges and training institutes.

Specifications

Typical Use

Gear pumps are found in lubrication systems, machine-tool hydraulics and mobile equipment, so the experiments carry over directly to what students will see in industry. On the module, the class runs the pump at several speeds, notes how delivered flow follows speed almost in step, and then raises the outlet pressure to observe the torque demand increase and the small drop in flow caused by leakage past the gear teeth. Working out the displacement per revolution from measured data, and comparing it with the value expected from the gear geometry, is a good exercise in engineering estimation.

For TVET and diploma courses that need mechanics lab equipment in India with a clear link to maintenance work, running the gear pump alongside a vane pump on the same module lets learners compare noise, flow smoothness and efficiency between the two designs. The self-sealing connections make that swap quick and tidy. Keep the oil topped up and clean, and never run the pump dry.

Manufacturer

The Gear Pump is produced by Jain Scientific Equipments Private Limited of Ambala, Haryana — the company behind the ScienceLab name — which designs and builds apparatus for engineering, science and vocational teaching. Find out more on the company profile page.

The Axial Flow Pump Module (Product Code: SLE/EFM/03) is a self-contained test rig built around an axial flow pump, mounted in a mobile frame with full instrumentation that includes a digital pressure display. It lets students study and test a common type of rotodynamic pump safely and at a realistic scale, without needing any external water supply. The module is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and is part of the engineering educational equipment we build for colleges in India and abroad.

Specifications

Typical Use

The core experiment is the pump characteristic: at a fixed speed, students throttle the flow in steps, record pressure rise and shaft power at each point, and plot head, power and efficiency against flow rate. Repeating the test at other speeds shows how the whole curve shifts and gives a practical introduction to the pump scaling laws. Axial flow pumps move large volumes against relatively modest heads, so comparing their curves with those of a centrifugal pump helps students understand why each design suits different duties, from drainage and irrigation to cooling-water circuits.

Because the module carries its own reservoir, it can be wheeled into any teaching space as lab equipment for college practicals without plumbing. Sharing one Universal Dynamometer across several Fluid Power modules keeps the cost of a full lab down, and the schematic on the connection plate helps students trace the circuit before they start. Check the reservoir level before each session and drain it for long storage.

The Francis Turbine (Product Code: SLE/EFM/04) is a teaching model of the reaction turbine found in many hydroelectric plants. Adjustable guide vanes control the water entering the machine and direct it at an angle onto the blades of a radial impeller, and a clear viewing window and draft tube let students watch the turbine working as they change the vane setting. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a technical educational equipment manufacturer supplying engineering departments and polytechnics.

Specifications

Typical Use

The Francis design is widely used around the world because it adapts to a wide range of applications, which makes it a natural centrepiece for hydraulic machines practicals. A typical session sets the guide vanes to one opening, loads the turbine in stages and records speed, torque and flow to build output and efficiency curves; the vanes are then moved to a new position and the test repeated. Students quickly see that each vane opening has its own best operating point, and why power stations adjust guide vanes rather than simply throttling the supply.

Being a reaction machine, the runner turns under both the pressure and the velocity of the water, unlike an impulse wheel. Watching through the window and down the draft tube, the class can relate swirl and flow pattern to efficiency and discuss how the draft tube recovers energy from the leaving water. For engineering lab equipment in India’s degree and diploma programmes, testing this turbine against a Pelton wheel gives a complete picture of reaction and impulse behaviour.

Manufacturer

Our Francis Turbine is made by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is headquartered in Ambala, Haryana. The firm builds hydraulics, mechanics and science apparatus for teaching laboratories; see the company profile for background.

The Pelton Wheel (Turbine) (Product Code: SLE/EFM/05) is an impulse turbine with tangential flow: a jet of water from a variable spear nozzle strikes a ring of paired buckets and drives the wheel round. A clear viewing window on the side lets students see exactly how the jet and buckets interact. Built by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is designed as lab equipment for college and polytechnic hydraulics courses studying high-pressure, low-flow machines.

Specifications

Typical Use

The variable spear jet is the key teaching control. Moving the spear changes the jet, and with it the velocity of the water hitting the buckets, so students can explore how jet speed, wheel speed and power output relate. A standard exercise records output across a range of wheel speeds at a fixed spear setting and then repeats the run at another setting, revealing that the wheel performs best when its bucket speed is a particular fraction of the jet speed — a result students can compare with impulse-momentum theory.

Watching through the side window, the class sees the jet split by each pair of buckets and turned back on itself, which explains why the buckets are paired: the split keeps side forces balanced and allows the water to leave with little remaining energy. Pelton wheels suit mountain hydro schemes with high heads and modest flows, so for vocational training lab equipment in India this turbine connects classroom theory with real installations. Contrasting it with a Francis reaction turbine rounds off the topic.

Manufacturer

Jain Scientific Equipments Private Limited manufactures the Pelton Wheel at Ambala in Haryana and sells it under the ScienceLab trading name to engineering and science teaching institutions. Learn more on our company profile.

The Universal Dynamometer (Product Code: SLE/EFM/06) is the shared drive and measuring unit for the Fluid Power machines. It pairs a trunnion-mounted induction motor, which reacts against a strain gauge load cell, with a motor drive and display unit that digitally shows speed, torque and shaft power. Because it couples directly to each machine, students spend their time taking readings rather than fitting belts and pulleys. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of our test and measuring instrument range for engineering teaching labs.

Specifications

Typical Use

In a Fluid Power lab the dynamometer is lifted onto whichever module is scheduled for the day — a pump, a compressor or another machine — and dropped onto the base-plate location points so the shaft lines up with the machine’s jaw coupling. Students then set the speed from the front panel and read torque, speed and shaft power directly. Because the motor is trunnion-mounted, the reaction torque on its casing is exactly what the load cell senses, so the displayed torque is the torque delivered to the machine; combining it with the machine’s own flow and pressure readings gives input power, output power and efficiency.

For institutions choosing TVET lab equipment in India, one dynamometer serving many modules is an economical way to build a complete fluid machines laboratory. The instrument outlets on the rear panel mean each module’s gauges draw power from the same unit, cutting down trailing mains leads and keeping the bench tidier and safer. Always press stop before swapping modules, and keep the rubber coupling element in good condition.

Manufacturer

The Universal Dynamometer is built by Jain Scientific Equipments Private Limited in Ambala, Haryana; the company’s products are branded ScienceLab and serve teaching labs at schools, colleges and technical institutes. Read about us on the company profile page.

The Reciprocating Compressor (Product Code: SLE/EFM/07) is a trolley-mounted test module containing a small compressor, an air receiver and instrumentation, used to show students how a piston compressor turns shaft power into compressed air. A valve and orifice on the receiver outlet let the class set delivery pressure and measure the mass flow of air leaving the system. The module is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as lab equipment for technical institutes, engineering colleges and industrial training centres.

Specifications

Typical Use

Reciprocating compressors supply the air behind air tools, paint spray equipment, pneumatic actuators and control systems, so this module links directly to what students meet in workshops and plants. In a typical test the compressor runs at a chosen speed while the outlet valve is closed in steps; at each receiver pressure the class records mass flow from the orifice and the power absorbed from the dynamometer. The resulting curves show how the flow the compressor can deliver falls as delivered pressure rises, and let students calculate volumetric efficiency and the power needed per unit of air.

Repeating the series at different speeds shows the effect of running a compressor faster or slower, a practical point for anyone who will later size or operate a plant compressor. As engineering educational equipment for Indian diploma and degree programmes, the trolley mounting lets one module move between rooms. Release receiver pressure fully after each session, keep the orifice clean, and keep hands clear of moving parts while the machine runs.

Manufacturer

This compressor module is produced by Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer whose apparatus is sold under the ScienceLab name. The company serves teaching laboratories across engineering and the sciences; visit our company profile to learn more.

A small compressor, an air receiver and instrumentation, all mounted on a robust mobile trolley.

Is the Universal Dynamometer part of the module?
No. It is a separate unit that measures speed, torque and the power absorbed by the compressor.

How is air flow measured?

The Two Stage (Series And parallel) apparatus (Product Code: SLE/EFM/08) is a two-pump centrifugal test rig in which students run each pump alone, or both together in series or in parallel, and measure how the combined system behaves. Each pump has its own motor, speed control, torque load cell and speed sensor, and flow is found from the differential pressure across a Venturi meter. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and forms part of our engineering lab equipment for India’s mechanical and civil engineering departments.

Specifications

Typical Use

Students usually begin with one pump, plotting head, power and efficiency against flow. They then switch the two-way valve to series and see the heads add at a given flow, before changing to parallel and seeing the flows add at a given head — the two classic results every engineer needs when designing a pumping station or booster system. Because each motor has its own speed control and torque measurement, the pumps can also be run at different speeds to show what happens when mismatched machines share a system.

Closing an inlet valve progressively lets the class see cavitation begin and hear the change in pump noise, giving a vivid lesson in suction conditions. The same rig teaches flow measurement: students convert the Venturi differential pressure into flow rate and compare the result with theory. Since water returns to the reservoir for re-use, water consumption stays low, which makes the rig well suited as lab equipment for college buildings without large drainage facilities. Clean the strainers regularly and refill the reservoir with clean water.

Manufacturer

Jain Scientific Equipments Private Limited, the Ambala, Haryana company behind the ScienceLab brand, makes this rig for teaching laboratories. Its corporate identity number is CIN U29309HR2020PTC087597, and apparatus is produced at the licensed works at 449, HSIIDC Industrial Area, Saha, Ambala, under Factory Licence AMB-ONLINE-CHD-J-414.

The Friction Loss In Pipe apparatus (Product Code: SLE/EFM/09) measures the pressure lost as water flows along a test pipe, across both laminar and turbulent regimes. Static pressure tappings either side of the pipe feed a water manometer for small differentials and a hand-held digital pressure meter for larger ones, while a precision needle valve sets the flow. The apparatus stands on a hydraulic bench and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for fluid mechanics courses at engineering colleges and polytechnics.

Specifications

Typical Use

Students set the apparatus on the hydraulic bench and fit the Header Tank, which provides a steady supply for the low-flow runs. Starting with the needle valve nearly closed, they read the head loss on the water manometer, collect a timed volume to find the flow rate, then open the valve a little and repeat. At low flows the head loss rises in direct proportion to velocity; as the flow increases past transition the relationship steepens, and the class switches to the digital pressure meter to follow the higher differentials in the turbulent region.

Plotting friction factor against Reynolds number turns the readings into a small Moody-style chart and lets students compare their laminar results with the theoretical Poiseuille line. As mechanics lab equipment for India’s civil and mechanical engineering syllabi, the apparatus supports reports on pipe design, pump sizing and energy loss. Use the hand-pump to bring the manometer levels to a convenient datum before each series, and bleed air from the tappings so readings settle quickly.

Manufacturer

Jain Scientific Equipments Private Limited produces the Friction Loss In Pipe apparatus in Ambala, Haryana, marketing it under its ScienceLab trade name to colleges and training institutions. More about the company is on our company profile.

The Bernoulli’s Theorem apparatus (Product Code: SLE/EFM/10) demonstrates the exchange between pressure and velocity as water passes through a horizontal Venturi tube. Manometer tubes held vertically on a scaled panel show the pressure head at points along the tube, so students can see pressure fall in the throat and recover downstream. Built with plastic materials and corrosion-resistant finishes, it is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as lab equipment for college and polytechnic fluid mechanics practicals.

Specifications

Typical Use

After levelling the base on its adjustable feet, students open the flow-control valve to set a steady flow and read the water level in each manometer tube against the panel scale. The heads drop towards the narrow throat of the Venturi, where velocity is highest, and rise again as the section widens. Using the measured flow and the tube cross-sections, the class calculates velocity head at each station and checks whether the total head stays constant, as Bernoulli’s equation predicts, or falls slightly because of friction.

Placing the control valve downstream keeps the approach flow undisturbed, so the readings reflect the Venturi itself rather than turbulence from a partly closed valve. If the water levels sit too high or too low on the scale, a hand-pump on the manifold air valve brings them back to a convenient datum. For engineering educational equipment in India, this apparatus also introduces the Venturi meter as a practical flow-measuring device, a topic students revisit in pump and pipe-network work. Drain the tubes after use and keep the panel scale clean.

Manufacturer

This apparatus is manufactured in Ambala, Haryana, by Jain Scientific Equipments Private Limited, whose ScienceLab brand covers fluid mechanics, physics and wider laboratory teaching equipment. Our company profile tells you more about who we are.

• Pipe Flow And Nozzle Kit — more pressure-velocity experiments in pipes and nozzles
• Two Stage (Series And parallel) — uses a Venturi meter for flow measurement in a pump rig

The complete Fluid Mechanics range lists further hydraulics apparatus.

Frequently Asked Questions

What does the Bernoulli’s Theorem apparatus include?
A horizontal Venturi tube, a downstream flow-control valve and manometer tubes on a panel, with a common manifold and air pressure-control valve, on a base with adjustable feet.

Why is the flow-control valve downstream?
So it does not cause any turbulence upstream of the Venturi, keeping the readings clean.

Viscosity And Particle Drag (Product Code: SLE/EFM/11) is a simple falling-sphere viscometer that shows students how the viscosity of a liquid resists a sphere dropping through it. The self-standing unit holds two glass tubes of test fluid side by side, so two liquids can be compared in one session without repeated draining and refilling. It is used in fluid mechanics teaching laboratories of engineering colleges, polytechnics and technical institutes, and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its engineering lab equipment in India.

Specifications

Typical Use

Students fill the two tubes with the liquids they want to study, pick a sphere whose density and size suit each fluid, and release it at the top of the column. Once the sphere has settled to a steady speed, they time it over the marked fall distance with a stopwatch. From the fall time they work out the terminal velocity and relate it to the drag on the sphere and the viscosity of the liquid — the classic Stokes’ law exercise. Running water in one tube and castor oil in the other makes the contrast between a thin and a thick fluid obvious to the whole group.

For consistent readings, let air bubbles clear before each drop, release the sphere along the centre of the tube, and repeat several drops per fluid to average the times. Because viscosity changes with temperature, note the room temperature with each data set. Departments looking for a viscosity measurement apparatus in India that also introduces particle drag will find the twin-tube layout saves bench time between groups.

Lift And Drag (Product Code: SLE/EFM/12) is a force balance for measuring the hydrodynamic force on a model placed in the water flow of a laboratory flume. Its balance assembly is an articulated parallelogram linked to a load cell, and a separate display unit shows the measured force. The apparatus is aimed at civil and mechanical engineering departments teaching how bodies in a moving fluid experience lift and drag, and it is built by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a maker of lab equipment for technical institutes.

Specifications

Typical Use

A test model is attached to the balance and lowered into the flow, and the carrier is rolled along the flume rails to place it in the working section. As water passes the model, the parallelogram linkage keeps the model’s orientation steady and passes only the fluid force to the load cell, so turning moments do not distort the reading shown on the display unit. Students change the flow rate or the model’s shape and orientation, record the force each time, and plot how it varies — the basis for discussing drag coefficients, streamlining and lift on inclined bodies.

Zero the display with the model in still water before each series, allow the flow to stabilise after every change, and keep the carrier rails clean so the assembly runs freely. As engineering lab equipment in India, the balance suits both undergraduate practicals and simple project work on bluff and streamlined shapes.

Manufacturer

ScienceLab is the brand under which Jain Scientific Equipments Private Limited of Ambala, Haryana, designs and supplies hydraulics teaching equipment such as this balance. The company is a registered MSME manufacturer (Udyam UDYAM-HR-01-0003714), and its overseas consignments move under DGFT Importer-Exporter Code AAECJ8618A.

Frequently Asked Questions

Is the flume included with Lift And Drag?
No flume is listed as part of this item; the balance is built to run on a flume’s rails with the display unit hung on the flume. Tell us which flume you have so we can check the fit.

Why use a parallelogram linkage instead of a simple arm?
The parallelogram resists bending moments, so only the force acting on the model is transmitted to the load cell, giving a cleaner force reading.

Does it read lift and drag at the same time?
The balance passes the model force to one load cell shown on the display unit. For the exact measuring arrangement for lift and for drag, please contact us.

Which test models come with the balance?
Models are not specified in our current product details; ask us for the model shapes available with your order.

How should the load cell be looked after?

Cavitation In Venturi (Product Code: SLE/EFM/13) is a self-contained, mobile teaching unit that produces clearly visible cavitation in a Venturi so students can watch vapour bubbles form and collapse while taking flow and pressure readings. It gives mechanical, chemical and civil engineering students hands-on practice with the continuity equation and Bernoulli’s equation in a setting where the theory visibly breaks down. The unit is produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, an engineering lab equipment manufacturer serving colleges and polytechnics.

Specifications

Typical Use

With the pump running, students open the flow-control valve step by step and read the flow meter together with the gauges upstream of the Venturi and at its throat. As velocity through the throat rises, throat pressure falls until it reaches the vapour pressure of the water and a cloud of bubbles appears. Comparing the measured pressure drop with the value predicted by the continuity and Bernoulli equations shows where simple theory holds and where losses and cavitation take over. Because vapour pressure depends on temperature, the tank thermometer reading is recorded with every set of results.

Classes can explore more than one way of bringing on cavitation and then discuss the sources of error in their calculations. Keep the splash cover in place while running, top up the tank with clean water, and let the pump stop before adjusting pipework. As lab equipment for college India departments, the unit wheels between rooms, so one set can serve several practical groups.

Manufacturer

Cavitation In Venturi is part of the hydraulics range made by Jain Scientific Equipments Private Limited, a private limited company in Ambala, Haryana, whose products carry the ScienceLab brand. For details of the company’s background and other product lines, visit our company profile.

• Calibration of a Pressure Gauge — shows students how the dial gauges they read actually work
• Pressure Measurement Bench — broader practice with pressure measuring methods
• Water Hammer Apparatus — a companion study of pressure effects in pipe flow

More hydraulics teaching units are listed in our Fluid Mechanics category.

Frequently Asked Questions

Does the unit need an external water supply or hydraulic bench?
No. It carries its own water tank, electric pump, flow-control valve and flow meter on one frame, so it works as a self-contained unit.

Where is pressure measured?
Pressure gauges read the pressure upstream of the Venturi and at the Venturi throat.

Why is there a thermometer on the tank?
Water temperature affects its vapour pressure and therefore when cavitation starts, so the thermometer lets students record it with each result.

Is it safe to run in a classroom?
The pump includes electrical protection and the tank has a splash cover to prevent spillage. Normal lab supervision still applies.

What electrical supply does the pump need?
Supply voltage is not given in our current product details; contact us with your local mains supply so we can confirm.

Can a calibration certificate be provided for the gauges?

Trapezoidal Flume (Product Code: SLE/EFM/14) is a clear acrylic flow-measuring flume with a 60° trapezoidal profile, intended for measuring discharge in an open channel with particular emphasis on low-flow situations. Because the body is transparent, students can watch the water surface change as it passes through the section rather than simply reading a number. It suits hydraulics and irrigation engineering teaching, and is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, whose engineering educational equipment is used in colleges across India.

Specifications

Typical Use

Measuring flumes work by narrowing the channel so the flow passes through critical depth; once that happens, a single upstream depth reading can be related to discharge. A trapezoidal section keeps useful sensitivity when only a little water is flowing, which is why this flume is chosen for low-flow gauging exercises such as small streams, irrigation furrows and drainage outlets. In the lab, students set a series of flow rates, read the upstream water level for each, and build a depth–discharge rating curve that they compare with the flow measured independently.

Seal the flume carefully in its channel so no water bypasses the section, level it before taking readings, and allow the flow to settle after each change. Clean acrylic with water and a soft cloth only, as solvents can craze clear plastics. Beyond routine practicals, the flume also serves as lab equipment for research in India on small-channel flow measurement.

Manufacturer

The flume is produced in Ambala, Haryana, by Jain Scientific Equipments Private Limited. ScienceLab is the company’s trading name for its educational and laboratory equipment, including open-channel hydraulics apparatus. Our company profile has more about who we are.

Centrifugal Fan Module (Product Code: SLE/EFM/15) is a trolley-mounted test rig for measuring how a centrifugal fan performs as its speed and airflow change. The module carries the fan and its instrumentation on a robust, mobile trolley, and it comes with three different impellers so students can compare blade designs on the same housing. It is designed for mechanical engineering turbomachinery and air-handling practicals, and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a technical educational equipment manufacturer.

Specifications

Typical Use

A standard practical holds the fan at a fixed speed and closes the slide-valve in stages, recording the pressure difference across the shaped inlet nozzle (which gives the airflow rate) together with the speed, torque and absorbed power from the Universal Dynamometer. From these readings students plot pressure rise, power and efficiency against flow, producing the fan characteristic curves covered in fluid machinery courses. Repeating the test at other speeds lets them check the fan laws, and swapping to each of the three impellers shows how blade shape changes the curves.

The interlocked housing means an impeller change can be done safely: switch off, open the housing, fit the next impeller and close it again before the motor will restart. Keep the inlet nozzle free of dust and obstructions, since its reading sets the flow for every result. Wheeling the trolley between labs makes one module practical for several batches of students.

Manufacturer

Engineering teaching rigs such as this fan module are built by Jain Scientific Equipments Private Limited, which operates as ScienceLab from Ambala in Haryana, India. You can read about our history and capabilities on the company profile.

Related Fluid Mechanics Equipment

Equipment that works with, or alongside, the fan module in a turbomachinery lab:

• Universal Dynamometer — measures the speed, torque and power absorbed by the fan
• Pipe Flow And Nozzle Kit — pipes that connect to a fan inlet for suction-flow tests; ask us to confirm pairing
• Axial Flow Pump Module — compares a different rotodynamic machine in the same course
• Reciprocating Compressor — contrasts a positive-displacement air machine with the fan

For pumps, turbines and more, open the Fluid Mechanics category.

Frequently Asked Questions

How many impellers are supplied?
Three different impellers are supplied with the fan, and they are interchangeable in the same housing.

Is the Universal Dynamometer part of this module?
The dynamometer provides the speed, torque and power readings and is also listed as a separate product. Please confirm in your enquiry whether you need it supplied with the module.

How is airflow measured and controlled?
Air enters through a shaped nozzle used to measure the airflow rate, and a slide-valve downstream sets how much air flows before it leaves to atmosphere.

Can students change the impeller safely?
Yes. An interlock on the fan housing stops the motor from running unless the fan is correctly assembled.

What is the maximum fan speed and power supply?
Speed is fully variable up to the fan’s maximum allowable value; the figures and mains requirement are not in our current listing, so please contact us.

Is a calibration certificate available for the instrumentation?

Self Regulating Siphon (Product Code: SLE/EFM/16) is a clear acrylic hydraulic model that shows a siphon adjusting its own discharge over a wide range while holding the upstream water level almost constant. Unlike a simple siphon that runs either full or not at all, this one passes a mixture of air and water, which is the key to its self-regulating behaviour. The model helps civil and water-resources engineering students understand siphon spillways used for level control, and it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its vocational training and engineering lab equipment.

Key Details

Typical Use

In a demonstration, the inflow to the model is raised in steps while students watch the siphon barrel through the transparent walls. At modest flows the siphon draws in air along with the water; as inflow increases, less air enters and more water passes, so the discharge rises while the upstream level barely moves. Recording the upstream level against discharge produces a remarkably flat curve, which students then compare with the steep level–discharge relationship of an ordinary weir or gate.

The model links neatly to real practice in canal and reservoir design, where siphon spillways protect structures from over-topping without moving parts. Fit it level and watertight in your channel, change flow slowly so each condition can settle, and rinse the acrylic with clean water after use. The mounting arrangement depends on your channel, so confirm fitting details with us before ordering.

Energy Dissipation (Product Code: SLE/EFM/17) is an open-channel accessory for studying how the energy of fast-moving water is dissipated below a hydraulic structure. It consists of a long apron and a selection of toothed and solid blocks that can be arranged in any combination on the apron, and it is designed to be used with the Spillway with Tappings. Civil and irrigation engineering departments use it to teach stilling-basin design, and it is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a TVET and engineering lab equipment manufacturer in India.

Key Details

Typical Use

Water leaving a spillway is fast and shallow, carrying enough energy to scour a riverbed if it is not tamed. With the apron placed downstream of the spillway, students first observe the flow and the hydraulic jump on the plain apron, then add toothed and solid blocks in different layouts and watch how the jump shortens, stabilises or moves. Measuring the water depths before and after the jump lets them calculate the energy lost for each arrangement and judge which layout performs best as a stilling basin.

Because the blocks can be arranged freely, groups can be set design challenges — for example, reaching a stable jump within the shortest length of apron. Record every layout with a sketch or photograph so results can be compared later, and dry the blocks before storage. The set is equally suited to TVET lab equipment lists for water-engineering diplomas and to degree-level hydraulics courses.

Manufacturer

The apron and block set is manufactured by Jain Scientific Equipments Private Limited, which trades as ScienceLab and operates from Ambala, Haryana. More about our work with engineering institutions is on the company profile page.

Water Hammer Apparatus (Product Code: SLE/EFM/18) lets students create and measure the pressure surge that travels along a pipe when flowing water is stopped suddenly. At its heart is a 60 m long coil of copper pipe with a solenoid valve at the discharge end; when the valve shuts, an electronic pressure transducer next to it captures the resulting pressure fluctuations. The apparatus serves mechanical and civil engineering courses on unsteady pipe flow, and it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, among its engineering educational equipment for Indian and overseas institutions.

Specifications

Typical Use

Students first set a steady flow through the coil with the downstream control valve and adjust the bypass valve to fix the mean pressure, reading it on the Bourdon gauge. Closing the solenoid valve then stops the water almost instantly, and the transducer records a sharp pressure rise followed by a decaying series of oscillations as the wave reflects back and forth along the pipe. From the period of these oscillations and the known pipe length they estimate the pressure-wave speed and compare the peak surge with the value predicted by Joukowsky’s equation.

The long coiled pipe stretches the wave’s travel time so it can be resolved clearly on a recording instrument. Before each session, use the bypass valve and Bourdon gauge to check the transducer calibration, and bleed trapped air from the pipe, as air pockets soften the surge. The rig is a practical choice among engineering educational equipment in India for showing why pipelines need surge protection.

Manufacturer

Jain Scientific Equipments Private Limited builds this apparatus under its ScienceLab label at Ambala in Haryana, where it develops pipe-flow and pressure teaching rigs for colleges and polytechnics. Find out more on our company profile.

Apparatus that pairs well with water hammer studies:

• Hydraulic Ram Pump — puts the water hammer effect to work to lift water
• Calibration of a Pressure Gauge — explains how the Bourdon gauge on this rig works
• Friction Loss In Pipe — covers steady pipe-flow losses before transients are introduced
• Cavitation In Venturi — another pressure effect students meet in pipe systems

See the rest of the Fluid Mechanics category.

Frequently Asked Questions

How long is the test pipe?
It is a coil of copper pipe 60 m long, which gives the pressure wave a measurable travel time.

Does it need a water supply?
Yes. The inlet connects to your water supply, and the bypass valve at the inlet end discharges to waste, so plan for a drain near the rig.

How are the pressure fluctuations recorded?
An electronic pressure transducer near the solenoid valve measures them. The display or recording instrument is not listed in our current details, so please contact us about readout options.

Can students check the transducer’s calibration?
Yes. The bypass valve sets the mean pipe pressure, which can be read on the Bourdon gauge and used to calibrate the transducer.

What electrical supply is needed for the solenoid valve and transducer?
Supply details are not in our current listing; tell us your mains supply through the contact page.

Is a calibration certificate supplied?
Any certificate requirement should be raised with us when you enquire, as availability depends on the order.

Do you ship outside India?
Yes, we supply institutions in India and international markets; include the destination and quantity in your enquiry.

Pipe Flow And Nozzle Kit (Product Code: SLE/EFM/19) is an air-flow accessory kit for studying pressure losses in pipes and fittings and for comparing different ways of measuring flow. The pipes connect to a fan inlet so the fan works in suction, drawing air through smooth-walled pipes fitted with many pressure tappings, a Pitot traverse, a nozzle and an orifice plate. It is intended for mechanical and aeronautical engineering practicals, and is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a supplier of lab equipment for college laboratories in India.

Specifications

Kit contents as described:

• Two long smooth-walled pipes with pressure tappings
• Pitot traverse
• Additional nozzle with axially moving probe assembly
• Orifice plate
• Two elbows and one bend

Typical Use

In the first exercise, students read static pressure at each tapping along a straight pipe and plot pressure against distance; the steady gradient gives the friction loss and, with the flow rate, the friction factor. Traversing the Pitot tube across the pipe end then gives the velocity profile, which they integrate to calculate the theoretical flow and compare with the readings from the nozzle and the orifice plate. Moving the probe step by step through the additional nozzle maps its axial pressure profile, showing how pressure converts to velocity as the flow accelerates.

Inserting the two elbows and the bend in turn between the long pipes isolates the extra pressure drop each fitting causes, so students can express it as a loss coefficient. Keep tapping tubes free of kinks, seal every joint well to avoid air leaks, and let the fan settle at each setting before reading.

Manufacturer

This kit is one of the air-flow teaching products developed by Jain Scientific Equipments Private Limited, known in the market as ScienceLab and located in Ambala, Haryana. Visit our company profile to learn about the organisation.

Culvert (Product Code: SLE/EFM/20) is a pair of clear culvert models — one of circular section and one of rectangular section — for observing and calculating how water passes through a culvert under a road or embankment. The models let students see both open flow, where the water surface stays free inside the barrel, and orifice flow, where the inlet is submerged and the culvert runs under pressure. The pair is used in civil engineering hydraulics and highway drainage teaching, and is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory equipment exporter from India.

Key Details

Typical Use

One model is set across the channel and the flow is increased gradually. At low flows the inlet is not submerged and the barrel carries a free-surface stream; as the upstream (headwater) level rises and covers the inlet, the culvert switches to orifice-type flow. Students record headwater depth against discharge through both regimes, identify the transition, and compare the measured values with open-channel and orifice equations. Repeating the test with the other model shows how a circular barrel and a rectangular box culvert differ in capacity and in how they fill.

Because the models are clear, air pockets, entrance contraction and the point where the barrel runs full can all be seen directly. Seal the model edges so water cannot slip past, set the channel level, and wait for the headwater to stabilise before each reading.

Manufacturer

Jain Scientific Equipments Private Limited, incorporated under CIN U29309HR2020PTC087597, makes these models under the ScienceLab name in Ambala, Haryana. Its production runs at the licensed factory in HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414). Read more on our company profile.

Frequently Asked Questions

How many models are in the set?
Two: one culvert of circular section and one of rectangular section.

What is the difference between open and orifice flow here?
In open flow the inlet is not submerged and the water has a free surface inside the barrel; in orifice flow the inlet is covered and the culvert behaves like an orifice under head.

Bridge Piers (Product Code: SLE/EFM/21) is a set of four differently profiled bridge piers with a pair of sediment walls, used to show what happens to a river flow as it squeezes past the supports of a bridge. With the piers in a channel, students can observe the increased flow velocity and the streamline curvature between the piers, and watch scouring of the stream bed develop around them. The set is used in civil engineering courses on river hydraulics and bridge design, and is built by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, which makes lab equipment for technical institutes.

Key Details

Typical Use

The sediment walls are placed across the channel to retain a layer of bed material, and one or more piers are set into it. When flow starts, the water speeds up through the narrowed openings between piers and the streamlines bend visibly around each nose. Over time a scour hole forms at the upstream face of each pier where the flow dives down and a horseshoe-shaped vortex lifts sediment. Students swap between the four profiles and compare how deep and how wide the scour becomes, and how strongly the water surface rises upstream.

Introducing a few drops of dye or small floating particles upstream makes the streamline curvature easy to photograph. Level the bed carefully before each run and keep the flow the same between profiles so comparisons are fair. The results connect directly to real decisions about pier shape and foundation depth on bridges over rivers.

Manufacturer

These pier models are made in Ambala, Haryana, by Jain Scientific Equipments Private Limited, the company behind the ScienceLab brand of educational and engineering apparatus. See our company profile for more information.

Sluice Gate with Tappings (Product Code: SLE/EFM/22) is a flume accessory that lets students measure the water pressure acting on the face of a sluice gate. Ten pressure tappings run across the gate face, so the pressure distribution can be read directly and related to the flow rate and the upstream depth. It is intended for use with a flume (not included) in civil engineering and irrigation hydraulics labs, and is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a scientific laboratory equipment manufacturer.

Specifications

Typical Use

The gate is installed across the flume with a set opening beneath it, and each tapping is connected to a manometer or pressure display. At a given discharge, students read the upstream depth and the pressure head at every tapping, then plot pressure against position down the gate face. Near the top of the water the readings follow the hydrostatic line, but closer to the gate lip the pressure drops below hydrostatic as the flow accelerates towards the opening — a result that simple textbook assumptions miss.

By changing the flow rate and gate opening, the class sees how the distribution and the total force on the gate change with depth, and can compare the measured force with a hydrostatic estimate. Flush the tapping lines to clear air bubbles before each run, since trapped air gives false readings, and allow the upstream level to settle after every adjustment.

Manufacturer

The gate is produced by Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer operating under the trade name ScienceLab. Our company profile explains more about the company and its product lines.

Meter Flume (Product Code: SLE/EFM/23) is a 300 mm wide open-channel flume, available in lengths from 5 to 15 m, for student study and advanced research across a wide range of fluid flow topics. It has its own built-in recirculating water supply with a digital flow meter, and pressure tappings along the working section for detailed measurement. The flume forms the backbone of a university or institute hydraulics laboratory, and a large range of ancillaries is available to extend what it can teach. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a producer of engineering lab equipment in India.

Specifications

Typical Use

A flume of this kind supports a full open-channel syllabus: uniform flow and Manning’s equation, specific energy and critical depth, hydraulic jumps, flow over weirs and under gates, and flow around structures such as culverts and bridge piers. Students set the discharge on the digital flow meter, install the structure being studied, and read water levels and the tapping pressures spaced every 0.25 metre along the working section to build surface and pressure profiles. Because the water recirculates, there is no need for a separate sump or mains supply during a session.

For research groups, the longer versions give more distance for flow to develop before it reaches a test model, and the 32-way pressure display option speeds up data collection. Keep the water clean to protect the flow meter, check that tapping lines are free of air before each run, and drain and dry the channel when it will stand unused. Choose the length that suits your room and experiments, and check ancillary fit with us when ordering.

Hydraulic Ram Pump (Product Code: SLE/EFM/24) demonstrates a pump with no motor at all: it uses the momentum of a large, slow-moving column of water to lift a smaller amount of water to a higher level. The apparatus has three main parts — a wall-mounted header tank, the pump, and the interconnecting pipework — with an inner and outer valve on the supply pipe and an air vessel to reduce hydraulic shock. It is used in mechanical, civil and agricultural engineering teaching, and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory instruments supplier in India.

Specifications

Typical Use

Water runs down the supply pipe from the header tank and escapes through the outer valve until its speed is enough to snap that valve shut. The sudden stop acts like a plunger: the moving column’s energy forces some water through the inner valve into the delivery pipe, the air vessel cushions the pressure pulse, and the cycle repeats on its own. Students measure how much water is delivered and how much is spilled at the outer valve, then calculate the pump’s efficiency from the flows and heads involved.

Adding weights to the outer valve platform changes how long each cycle lasts, so the class can investigate how cycle time affects delivered flow and efficiency. Fix the header tank securely to a wall that can carry its full weight of water, keep the valves free of debris, and check the air vessel still holds air if the pump becomes noisy. The ram pump is a memorable way to show how the water hammer effect can be turned into useful work in places without electricity.

Manufacturer

Our hydraulic ram apparatus is manufactured by Jain Scientific Equipments Private Limited, better known by its ScienceLab brand, in Ambala, Haryana. Registered as an MSME manufacturing enterprise (Udyam UDYAM-HR-01-0003714), the company ships overseas orders under DGFT Importer-Exporter Code AAECJ8618A.

• Stopwatch, Digital — times volume collection and valve cycles
• Measuring Cylinder 1000 ml — collects delivered and spilled water to find flow rates
• Vane Pump — a motor-driven pump for contrast with the ram principle

See more hydraulics apparatus in the Fluid Mechanics category.

Frequently Asked Questions

Does the ram pump need electricity?
No. It is not a normal mechanically-operated pump; it runs on the momentum of water flowing down from the header tank.

What is supplied?
The header tank, the pump with its inner and outer valves and air vessel, the interconnecting pipework, and the weights for the outer valve platform.

How is the header tank installed?
It mounts to a suitable wall, so plan a sturdy wall location near a water supply and drain.

What do the weights do?
Loading the outer valve platform with the weights provided changes the pump’s cycle times, letting students study their effect on performance.

What delivery height can it achieve?

Calibration of a Pressure Gauge (Product Code: SLE/EFM/25) is a teaching apparatus that shows both how a Bourdon-type pressure gauge works and how it is calibrated. A gauge with a transparent dial, so its working mechanism is on view, is connected to a dead weight tester; students load known weights, calculate the pressure they produce and compare it with the gauge reading. It introduces the principles of lab equipment calibration to mechanical, instrumentation and civil engineering students, and is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

Students add weights to the dead weight tester platform in increments, and at each step they calculate the true pressure from the total load and the known piston area and write down the gauge reading. They then remove the weights step by step and record the readings again on the way down. Plotting gauge reading against true pressure for loading and unloading reveals the gauge’s error at each point and any hysteresis, and lets them draw up a correction chart.

Watching the oval tube through the clear dial as it tries to straighten under pressure makes the Bourdon principle easy to grasp, and many students meet this mechanics lab equipment before using dial gauges on larger rigs. Place the weights gently and centrally, rotate the piston slightly while readings are taken if the design allows, and make sure no air is trapped in the water-filled flexible tube.

Manufacturer

The apparatus is designed and built in Ambala, Haryana, by Jain Scientific Equipments Private Limited, which markets its instruments as ScienceLab. More details are on our company profile.

Related Laboratory Equipment

Pressure-measurement equipment that students use alongside this experiment:

• Bourdon Gauge — a stand-alone gauge of the same type for other pressure demonstrations
• Pressure Measurement Bench — compares different pressure-measuring methods
• Water Hammer Apparatus — applies a Bourdon gauge and a transducer in a working pipe rig
• Cavitation In Venturi — uses dial gauges to track pressure at a Venturi throat

Browse our Fluid Mechanics category for more.

Frequently Asked Questions

How is the pressure worked out during calibration?
The weights put a known force on a piston of known area, so pressure equals that force divided by the piston area.

Can students see inside the gauge?
Yes. The dial is transparent, so the oval tube, its fixed end and the pointer linkage are all visible.

What fluid is used in the system?
A flexible tube containing water transfers the pressure from the piston to the gauge tube.

What pressure range does the gauge cover?
The range and the weight set details are not listed in our current product information; contact us for these figures.

Does the apparatus come with a calibration certificate?
It is built to teach calibration rather than serve as a reference standard; talk to us about any certificate needs when you enquire.

How should it be maintained?
Keep the piston and cylinder clean, store the weights dry, and top up or bleed the water-filled tube if readings become erratic.

What should an institutional enquiry include?
Quantity, delivery location in India or abroad, and any tender format; we will reply with a formal quotation.

The Pressure Measurement Bench (Product Code: SLE/EFM/26) is a two-unit teaching apparatus that lets students investigate and compare vertical and inclined U-tube manometers with Bourdon-type vacuum and pressure gauges, and then see how a Bourdon gauge is calibrated. Because manometers and Bourdon gauges sit inside more complex instruments such as pneumatic comparators and flow indicators, the bench gives mechanical and instrumentation students a clear grounding in how these devices work before they meet them in larger systems. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as lab equipment for technical institutes, engineering colleges and polytechnics.

Key Details

Typical Use

In a typical practical, students use the syringe assembly to apply a small positive pressure or a partial vacuum and read the vertical U-tube, the inclined-limb manometer and the matching Bourdon gauge side by side. Comparing the readings shows why an inclined limb spreads a small pressure change over a longer length of scale, why liquid-column instruments suit low pressures, and how a mechanical dial gauge responds to the same input. Changing the syringe setting slowly and letting the liquid columns settle before reading gives more consistent results.

The second half of the session moves to the calibration unit. Students load the dead-weight apparatus, note the Bourdon gauge reading against the known applied pressure, and build a calibration table or curve while watching the curved Bourdon tube move the pointer. The bench is well suited to fluid mechanics and instrumentation courses that need engineering lab equipment in India for both demonstration and small-group work.

Manufacturer

This bench is built by Jain Scientific Equipments Private Limited, a company based in Ambala, Haryana, that trades under the name ScienceLab and makes apparatus for engineering, science and technical teaching laboratories. Background on the company and its range is available in our company profile.

Explore the full Fluid Mechanics range for flow, pump and turbine apparatus.

Frequently Asked Questions

What is included with the Pressure Measurement Bench?
Two units: the manometers and gauges unit (vertical U-tube manometer, inclined-limb U-tube manometer, vacuum Bourdon gauge, pressure Bourdon gauge and syringe assembly on a framed backboard) and a separate Bourdon gauge calibration unit with dead-weight apparatus.

Why are there two different manometers?
So students can compare them directly. Tilting one limb makes the liquid travel further along the scale for the same pressure change, which makes small pressures easier to read than on a vertical U-tube.

Can the bench show vacuum as well as positive pressure?
Yes. One Bourdon gauge measures vacuum and the other positive pressure, and the syringe assembly can both raise and reduce the pressure applied to the instruments.

What pressure ranges do the gauges cover?
Gauge ranges and the manometer fill liquid are not stated in our current product description. Please contact us for the detailed datasheet before ordering.

Can a calibration certificate be supplied with the gauges?
This depends on the order; please discuss your requirement with us through the contact page at the enquiry stage.

What should we include in a request for an institutional quotation?
Tell us the number of benches, the delivery address or port, and any tender format you must follow. Warranty terms are stated in the quotation itself.

Do you supply multiple benches or ship abroad?
Yes. We supply colleges and training centres across India and international markets; quantities, packing and dispatch time are confirmed when we quote.

The Vortex Appartus (Product Code: SLE/EFM/27) is a rotating-vessel apparatus for producing a forced vortex in water and measuring the shape of its free surface. A low-voltage, variable-speed motor spins the vessel about its vertical axis, and a traverse probe with linear scales lets students map the surface profile point by point. Designed for fluid mechanics teaching in engineering colleges, polytechnics and technical training centres, it is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, an engineering lab equipment manufacturer serving institutions in India and abroad.

Key Details

Typical Use

Students start the vessel turning, add water until it is roughly half full and watch a forced vortex develop: the water surface falls steeply towards the centre and can open up an air core. After a few minutes of steady rotation the vortex settles into a constant shape, and only then do students take readings, stepping the traverse probe across the radius and recording the surface height against radial position from the two scales. Repeating the traverse at different motor speeds shows how the surface profile deepens as rotation increases, and the results can be compared with the parabolic profile predicted by forced-vortex theory.

For a second set of readings the traverse probe is swapped for a Pitot tube, so the class can plot how total head varies across the vessel. Keeping the speed-control unit away from the vessel lets the instructor adjust rotation without disturbing the water, which makes the apparatus practical for group demonstrations as well as individual lab reports. It suits institutions building engineering educational equipment into their hydraulics and fluid mechanics syllabus.

Manufacturer

ScienceLab is the brand name used by Jain Scientific Equipments Private Limited of Ambala, Haryana, which produces this vortex apparatus along with other fluid mechanics and structures teaching equipment. You can learn more about who we are on our company profile page.

Other items that complement vortex experiments in the same hydraulics lab:

• Bernoulli's Theorem — builds on the total-head idea with a Venturi tube and manometer panel
• Cavitation In Venturi — links pressure, velocity and flow in a visible demonstration
• Pressure Measurement Bench — grounds students in manometer and gauge readings before head measurements
• Stopwatch, Digital — for timing how long the vortex takes to settle before readings are taken

The complete Fluid Mechanics category lists our pumps, flumes and flow apparatus.

Frequently Asked Questions

How is the speed of the vessel controlled?
Through a separate speed-control unit placed away from the main apparatus, which drives the low-voltage, variable-speed motor.

How do students measure the vortex surface?
With the traverse probe, which moves both horizontally and vertically; each axis has a linear scale, so surface height can be recorded at known radial positions.

Is a Pitot tube supplied?
The apparatus is designed so a Pitot tube can replace the traverse probe for total-head measurements. Please contact us to confirm whether it is part of your supply.

What are the vessel size and motor supply voltage?
These values are not listed in our current product description. Ask us for the datasheet through the contact page.

How long before readings can be taken?
Allow a few minutes of steady rotation; once the vortex shape stops changing, the surface profile can be traversed.

What warranty and documentation come with it?
Warranty terms are confirmed on the quotation. If you need instruction material or a calibration certificate for any measuring part, raise it with us before ordering.

Can you supply this to overseas institutions?
Yes, we deliver to colleges and training centres in India and international markets; export packing and shipping details are agreed at the quotation stage.

The Center of Pressure apparatus (Product Code: SLE/EFM/28) is a pivoted clear plastic assembly that students use to find the centre of pressure on a plane surface when it is totally or partially submerged in water. A clear quadrant mounted on a vertical panel holds the water, a scale shows the head, and weights hung from a lever arm balance the hydrostatic moment. Compact and self-contained, it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for hydrostatics practicals in engineering colleges, polytechnics and other buyers of mechanics lab equipment.

Key Details

Typical Use

The experiment works because of the quadrant's shape. Its curved sides are centred on the pivot, so the water pressure acting on them passes through the pivot and produces no turning effect; the only moment left is the one from pressure on the flat test face. Students add water in stages, read the head from the panel scale, and restore balance by adding weights to the lever arm. From the balancing moment they calculate the hydrostatic thrust and the depth of the centre of pressure, then compare it with the theoretical value for a partially submerged face and, once the water covers the face completely, for a fully submerged one.

Using the engraved lines, the plane can also be set at an angle to study inclined surfaces, a useful extension for civil and mechanical engineering groups. Level the panel before starting, add water gently to avoid splashing onto the balance side, and drain and dry the quadrant after the session to keep the clear plastic free of marks. The unit is a practical choice of lab equipment for college fluid mechanics courses that need a bench-top hydrostatics experiment.

Manufacturer

This apparatus comes from Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer operating under the ScienceLab brand. For tender and vendor registration forms, the company's GSTIN is 06AAECJ8618A1ZT and its Legal Entity Identifier (LEI) is 3358004HRD1JIVXKYX49. More about the business is on our company profile.

Useful additions for a hydrostatics and pressure practical:

• Pressure Measurement Bench — manometers and Bourdon gauges for the pressure-measurement part of the same module
• Calibration of a Pressure Gauge — a dead-weight tester that relates known forces and areas to pressure
• Hangers with Slotted Weights — extra slotted weights if more balancing increments are needed (check fit with us)
• Measuring Cylinder, Polypropylene — an unbreakable cylinder for adding water to the quadrant in controlled steps
• Bernoulli's Theorem — the natural next step from fluid statics into flowing water

Browse our Fluid Mechanics equipment for further hydraulics apparatus.

Frequently Asked Questions

Why do the curved faces of the quadrant not affect the result?
Their central axis coincides with the moment measurement axis, so the fluid pressure on them produces no moment about the pivot. The measured moment comes only from pressure on the plane test surface.

Can inclined plane surfaces be tested?
Yes. Engraved lines on the quadrant help students hold the plane either vertical or at an angle.

Are the balance weights included?
The moment is measured with weights on a lever arm, but the weight set supplied is not detailed in our current description. Please contact us to confirm contents.

Does it need a water supply or hydraulic bench?
It is a self-contained unit; water is added directly to the quadrant, so a simple container or measuring cylinder is enough.

How should the clear plastic parts be cleaned?
Drain after use and wipe with a soft cloth and plain water; avoid abrasive pads or solvents, which can scratch or cloud clear plastics.

Is a calibration certificate or warranty provided?
Both are handled per order. Discuss certificate needs with us, and the warranty period will be stated in your quotation.

Can several units be ordered for a class?
Yes, multiple sets can be supplied for colleges and institutes across India and international markets; share the quantity when you enquire.

Variable Speed Series And Parallel Pumps (Product Code: SLE/EFM/29) is a bench-top test set for studying how centrifugal pumps perform on their own and when two are combined in series or in parallel. It pairs one variable speed and one fixed speed centrifugal pump, each driven independently by its own bearing-mounted motor, drawing from a clear acrylic reservoir. The set is built for fluid machinery and hydraulics laboratories in engineering and diploma institutions by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a technical educational equipment manufacturer.

Key Details

Typical Use

A standard sequence begins with one pump running alone. Students close the delivery valve in steps, recording flow at each setting to build the pump's characteristic, then repeat at different speeds on the variable speed pump to see how the curve shifts. Next they valve the two pumps into series, which adds head for the same flow, and then into parallel, which adds flow at a similar head. Plotting all the curves on one chart makes the difference between the two arrangements clear and shows why the choice matters when matching pumps to a real piping system.

Because one pump is variable speed and the other fixed, the set also lets students explore what happens when unequal pumps share a duty, a situation common in building services and water supply. The inlet valves can be throttled to create more demanding suction conditions. With a closed water circuit and a transparent reservoir, it is a tidy, visible choice of engineering lab equipment in India for colleges, polytechnics and TVET centres.

Manufacturer

The pump set is produced under the ScienceLab name by Jain Scientific Equipments Private Limited, whose operations are in Ambala, Haryana, India. Our company profile describes the wider range of engineering and science teaching equipment we make.

Related Fluid Mechanics Equipment

Apparatus often chosen with this set for a fluid machines course:

• Two Stage (Series And parallel) — an alternative two-pump rig that uses a Venturi meter for flow measurement
• Axial Flow Pump Module — contrasts centrifugal behaviour with a different rotodynamic pump type
• Cavitation In Venturi — shows the cavitation limits that affect pump suction design
• Friction Loss In Pipe — measures the pipe losses that make up the system curve a pump works against

See every item in our Fluid Mechanics category.

Frequently Asked Questions

Can each pump be run on its own?
Yes. Each pump has its own bearing-mounted motor, so either can run alone, or both can be combined in series or in parallel.

Why is one pump variable speed and the other fixed speed?
It lets students see how speed changes a pump's performance and how two unequal pumps behave when they share the same flow path.

What is measured on the set?
Water is delivered to a flow and temperature measurement device. Details of any pressure or head instrumentation, and of motor ratings, are not in our current description, so please contact us for the datasheet.

Does it need a mains water connection?
No continuous supply is described: the pumps draw from the clear acrylic reservoir and the water returns there for re-use.

How should the reservoir be maintained?
Use clean water, drain the reservoir if the set will stand unused for long periods, and wipe the acrylic with a soft cloth to keep it clear.

What details help with a tender or institutional quotation?
Send the quantity, installation site, electrical supply available at your lab and any tender specification sheet. Warranty terms are included in our quotation.

Is export supply possible?
Yes, the set can be supplied within India and to international markets; shipping arrangements are agreed when you order.
