The simple Pitot tube does not measure the________________?
Correct answer: D. All A., B. and C.
- A. Static pressure
- B. Dynamic pressure
- C. Velocity at the stagnation point
- D. All A., B. and C.
Explanation
A simple Pitot tube senses stagnation pressure, while static and dynamic pressures require separate pressure measurement or comparison. The fluid velocity at the stagnation point is zero, so the tube does not measure the upstream velocity there; hence all three listed quantities are not directly measured.
