A. Ambient temperature
B. Total pressure
C. Static velocity
D. Static pressure
I got this question during an internship interview.
Asked question is from Measurement of Velocity in a Compressible Flow in division Normal Shock Waves of Aerodynamics
Explanation: The velocity of sound can be calculated using the Pitot tube which measures the stagnation, also called total pressure and measuring the static pressure as well. There is no need to find temperature. And static velocity is nothing but zero velocity.
