When a Pitot tube is placed in a supersonic flow, there is a normal shock wave immediately upstream of the probe. A Pitot tube on a supersonic aircraft senses a stagnation pressure pâ‚€ = 200 kPa and a static pressure p = 160 kPa downstream of the shock wave. The stagnation temperature is 400 K. Consider the following:
i) Determine the Mach number upstream of the shock wave.
ii) Calculate the aircraft velocity (m/s).
