A normal shock is positioned inside a converging- diverging nozzle of throat area 5 cm, run by a settling chamber with air at 5 atm and 330 K. If the pressure loss caused by the shock is 12.4% (P01-P02) x 100 = 12.4 and the temperature at the nozzle exist is 300 K, determine : [(Po= P01 a. The Mach number ahead of the shock b. The flow speed behind the shock and at the nozzle exit c. The mass flow rate through the nozzle ***
