Which of the following is the correct formula for dynamic pressure?(a) q=\(\frac{1}{2}\)γPM^2(b) q=\(\frac{1}{2}\)γρM^2(c) q=\(\frac{1}{2}\)γPV^2(d) q=\(\frac{1}{2}\)γρV^2This question was posed to me during an interview.This interesting question is from Air Data Computers in division Atmosphere and Air Data Measurement of Aircraft Performance

Answer»

Right CHOICE is (a) q=\(\frac{1}{2}\)γPM^2

The best explanation: The correct formula for DYNAMIC pressure is 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.
