Air flows through a converging and diverging nozzle with an area ratio (exit to throat) of 3.5. The upstream stagnation conditions are atmospheric, and the back pressure is maintained by a vacuum system. Find: (a) The mass flow rate if the throat area is 500 mm2 . (b) The range of back pressures for which a normal shock will occur within the nozzle.
