Question:

A Pitot-static tube is used to measure the Mach number on a supersonic aircraft . The tube, because of its bluntness, creates a normal shock wave as shown. The absolute total pressure downstream of the shock wave (pt2) is 150 kPa. The static pressure of the free stream ahead of the shock wave (p1) is 40 kPa and is sensed by the static pressure tap on the probe. Determine the Mach number (M1) graphically.
