Question:

Air enters a converging-diverging nozzle at 700 K and 1000 kPa with negligible velocity. The exit Mach number is designed to be 2 and the throat area is 20 cm2. Now suppose the air experiences a normal shock at the exit plane. Determine
(a) The total pressure (p) after the shock,
(b) Mass flow rate () and
(c) The exit velocity.
