Question

For compressible flow also, we can calculate velocity with the Pitot and static pressure found.

(a) False

(b) True

The question was posed to me in unit test.

The query is from Measurement of Velocity in a Compressible Flow in section Normal Shock Waves of Aerodynamics

Answer 1

Correct option is (a) False

To elaborate: For the compressible flow- both supersonic and subsonic, we can calculate the Mach number by using the Pitot tube. It measures the total pressure and by measuring the static pressure we can get the Mach number, not velocity, unlike the incompressible flow.
