Problem 2 (25 points): Air enters an inlet after passing through two oblique shocks (OS) and a single normal shock (NS), as shown in the figure. The flight atmospheric total pressure is Po = 7.824 atm.
a-20 pts) Calculate the total pressure and the Mach number after the shock waves.
b-5 pts) What would have been the total pressure if the flow was slowed down using a single normal shock wave?
Use gas constant, R = 287 J/kg.K, specific heat ratio, y = 1.4.
