Question

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^2

This 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 1

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.
