The pitot tube is used to measure-

  1. Velocity at stagnation point 
  2. Stagnation pressure
  3. Static pressure
  4. Dynamic pressure

Answer: B. Stagnation pressure

The pitot tube is used to measure stagnation pressure.

Solution

Pitot tube:

  • Pitot tube is an instrument which is used to measure stagnation pressure at any point in the pipe.
  • Pitot tube measures velocity at any point but not at the stagnation point because the velocity at the stagnation point is zero.
  • Pitot tube works on the principle that when fluid strikes to a pitot tube, velocity of fluid becomes zero and it converts into the pressure head and change in the piezometric head is observed.
