Pilot Static Tube Set Up
Product Code : EL-FML-11045
Quick answer: The pitot static tube set-up measures point velocity inside a pipe. A pitot tube on a vernier scale traverses a clear acrylic 1 inch test section, and a U-tube manometer gives the velocity head, so students can calibrate the tube and plot the velocity profile across the pipe. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How the pitot tube experiment is done
A pitot tube facing the flow brings the water at its tip to rest and converts the local velocity into pressure, so the manometer reading above static pressure is the velocity head h and the point velocity is v = Cv sqrt(2 g h). The coefficient Cv, close to 1 for a well-made tube, is what the calibration finds.
In a pipe the velocity is highest at the centre and falls towards the wall. For laminar flow the profile is a parabola and the mean velocity is half the centre value; in turbulent flow it is much flatter, with the mean roughly 0.8 to 0.85 of the centre value. Comparing the centre reading with the mean velocity from the measuring tank shows which regime the bench is in.
- Start the pump and set a steady flow with the control valve.
- Set the pitot tube at the pipe centre using the vernier scale.
- Read the velocity head on the U-tube manometer.
- Traverse the tube across the pipe, recording the head at each position.
- Measure the discharge with the measuring tank and stop watch, and compare it with the integrated profile.
