Solution
Stagnation pressure is measured by a Pitot tube whose inlet is perpendicular to the turbulent flow.
Here's a step-by-step explanation:
-
Stagnation pressure is the pressure a fluid particle experiences at a point when it is brought to rest isentropically.
-
A Pitot tube is a device used to measure fluid flow velocity. It has two tubes: one open at the end and pointed into the flow (the stagnation or Pitot tube) and another with an opening on the side (the static tube).
-
When the inlet of the Pitot tube is perpendicular to the flow, the fluid particles are brought to rest (stagnate) at the opening of the tube. This is because the fluid particles have no place to go but into the tube, and they can't enter the tube because the tube is not moving.
-
The pressure measured at this point is the stagnation pressure. It is higher than the fluid's static pressure because it includes the dynamic pressure due to the
