Guess the Mach Number M. Determine the free stream static pressure using the Rayleigh-Pitot formula and the measured pressure from the pitot probe. ( [ ) ( ) [ The pressure ratio across the oblique shock is then With the Mach number and half wedge angle as the input, we can determine the pressure ratio across the oblique shock using the obshk program.
