The pressure difference (p0-p1) holds good only for incompressible flow.

(a) True

(b) False

I have been asked this question in an international level competition.

This key question is from Pitot Tube topic in section Inviscid & Incompressible Flow of Aerodynamics

The correct option is (a) True

Easiest explanation: The difference between total pressure (p0) and static pressure (p1) gives dynamic pressure holds true only for incompressible flow. The Bernoulli’s equation cannot be solved for compressible flow and also the pressure difference is not equal to dynamic pressure (q).
