(a) True

(b) False

The question was asked in quiz.

My question is taken from Air Data Computers in portion Atmosphere and Air Data Measurement of Aircraft Performance

Answer 1

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.
