Find the flow speed of air when the dynamic pressure is 70516 N/m^2 and density is 1.23kg/m^3.(a) 338.62 m/s(b) 340 m/s(c) 313.5 m/s(d) 321.5 m/sThis question was posed to me at a job interview.This intriguing question comes from Air Data Computers in portion Atmosphere and Air Data Measurement of Aircraft Performance

Answer»

Correct ANSWER is (a) 338.62 m/s

For explanation I WOULD say: The answer is 338.62 m/s. GIVEN dynamic pressure=70516 N/m^2 and density is 1.23kg/m^3. From the formula q=\(\frac{1}{2}\)ρV^2, substitute the given values.

On solving we GET 70516=\(\frac{1}{2}\)*1.23*V^2

V=338.62 m/s.
