Dynamic pressure is the difference between stagnation pressure and static pressure.(a) True(b) FalseThe question was asked in quiz.My question is taken from Air Data Computers in portion Atmosphere and Air Data Measurement of Aircraft Performance

Answer»

The correct choice is (a) True

Explanation: DYNAMIC pressure is the difference between stagnation pressure and static pressure. In simpler way it is kinetic energy per unit volume of a FLUID particle. It is REPRESENTED by ‘q’. The formula for dynamic pressure is given by q=\(\frac{1}{2}\)γPM^2 where q=dynamic pressure, P is pressure of the fluid, M is mach NUMBER of that medium and γ is the ratio of SPECIFIC heat at constant pressure to that of specific heat at constant volume.
