The Prandtl Pitot tube measures the__________________?
Correct answer: C. Velocity at a point in the flow
- A. Average flow velocity
- B. Pressure at a point
- C. Velocity at a point in the flow
- D. Pressure difference in pipe flow
Explanation
A Prandtl-Pitot tube compares stagnation and static pressure to determine the local fluid velocity at the probe position. It does not directly measure the average velocity across the pipe.
