Pitot Static Tube
Product Code : EL-EFFCA-11071
Quick answer: The pitot static tube measures local water velocity in the Lab Exports experimental flume. It reads total and static pressure at one point, and the difference shown on twin tube manometers (2 x 0-350 mm WS) gives the velocity. A holder with a 0-240 mm scale sets the depth for velocity profiles. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How the velocity profile is measured
The pitot-static tube has a forward-facing opening that senses total pressure and side holes that sense static pressure. By Bernoulli's equation the difference between them is the dynamic pressure, so the local velocity is v = sqrt(2 g dh), where dh is the difference between the two manometer columns in metres of water.
In an open channel the velocity is not uniform: it is lowest near the bed and walls and highest a little below the surface. Traversing the tube vertically and integrating the readings over the flow area gives a discharge that students can check against the flume's rotameter.
- Fix the carrier at the chosen station along the experimental section.
- Bleed the hoses and manometer tubes so that no air is trapped.
- Lower the tube to the first depth on the vertical scale, facing upstream.
- Read the two manometer columns and note the difference.
- Step through the depth and repeat, then plot velocity against height.

Frequently asked questions
How is velocity found with a pitot static tube?
The manometers show total and static pressure; the difference is the dynamic pressure, and the velocity is v = sqrt(2 g dh).
Can the tube measure at different depths and positions?
Yes. The carrier fixes at any station along the flume, and the tube moves vertically against a 0-240 mm scale.
