Calculate the dynamic pressure of aircraft in air when density and flow speed are 1.23 kg/m^3 and 340m/s.(a) 71094 N/m^2(b) 54128N/m^2(c) 65487 N/m^2(d) 65789 N/m^2This question was posed to me during an interview for a job.This interesting question is from Air Data Computers topic in portion Atmosphere and Air Data Measurement of Aircraft Performance

Answer»

The CORRECT answer is (a) 71094 N/m^2

The BEST explanation: The answer is 71094 N/m^2. GIVEN speed=340m/s, ρ=1.23kg/m^3. On substituting the values in the formula q=\(\frac{1}{2}\)ρV^2.

We GET q=\(\frac{1}{2}\)*1.23*340^2

On solving we get q=71094 N/m^2.
