Air enters a convergent–divergent nozzle at 20 × 105 N/m2 and 40°C. The receiver pressure is 2 × 105 N/m2 and the nozzle throat area is 10 cm2.
(a) What should the exit area be for the design conditions above (i.e., to operate at third critical?)
(b) With the nozzle area fixed at the value determined in part (a) and the inlet pressure held at 20 × 105 N/m2 , what receiver pressure would cause a shock to stand at the exit?
(c) What receiver pressure would place the shock at the throat?
