Air at a pressure of 90 psia and a temperature of 250 F enters an ideally designed converging-diverging nozzle from a large plenum chamber. The air is supposed to expand to ambient pressure without any shock wave present. (Assume isentropic expansion of dry air). Find (a) the area of the nozzle throat in square inches that will permit a mass flow rate of 3.0 lbm/s and (b) the Mach number and area at the nozzle exit
