Friction In Pile Lines Apparatus
Product Code : EL-FML-11042
Quick answer: The friction in pipe lines apparatus measures the head lost to wall friction in two GI pipes, 1/2 inch and 1 inch, each over a 1 m test length. Students read the loss on a differential manometer, time the flow in a measuring tank and calculate the Darcy friction factor. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How the pipe friction experiment is done
Water flowing along a pipe loses energy to shear at the wall. The Darcy-Weisbach equation, hf = f L v^2 / (2 g D), links this head loss to the pipe length L, the diameter D and the mean velocity v through the friction factor f. Rearranged as f = 2 g D hf / (L v^2), it lets students work out f from their readings and see how it changes with Reynolds number, Re = rho v D / mu.
Testing a 1/2 inch and a 1 inch pipe over the same 1 m length shows the strong effect of diameter: at the same discharge the smaller pipe carries the water much faster and loses far more head. Comparing results with the Blasius relation or a Moody chart connects the bench to real pipeline design.
- Open the control valve for the pipe under test and close the other.
- Start the pump and set a flow with the flow control and by-pass valves.
- Read the head loss over the 1 m test length on the differential manometer.
- Time the rise in the measuring tank to find the discharge and velocity.
- Repeat at several flows and for the second pipe, then plot f against Re.
