Lift And Drag
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
| Parameter | Detail |
|---|---|
| Balance type | Articulated parallelogram linked to a load cell |
| Force path | Parallelogram resists bending moments so only the force on the model reaches the load cell |
| Mounting | Balance assembly sits on a carrier that runs along the rails of the flume |
| Readout | Display unit showing the force measured by the load cell |
| Display mounting | Display unit hangs on the flume |
| Used with | A laboratory flume with rails (flume not listed as part of this item) |
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.

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?
Avoid knocking or overloading the balance, dry the assembly after use and store it off the flume when the lab is idle.
What warranty applies?
Warranty terms are given with the quotation; contact us for current terms.
What should an institutional enquiry include?
Share the quantity, your flume details, delivery location and any tender documents required, and we will respond with a formal offer.
