A cоnverging-diverging nоzzle is designed tо operаte isentropicаlly with аn exit Mach number of 1.5. The nozzle is supplied from an air reservoir in which the pressure is 500 kPa; the temperature is 400 K. The nozzle throat area is 5 cm2. Assume air to behave as a perfect gas with  = 1.4 and R = 0.2870 kJ/kg·K. (a) Determine the ratio of exit area to throat area. (b) Given the area ratio in part (a), find the range of back pressure over which the nozzle is choked. (c) Determine the mass-flow rate for a backpressure of 450 kPa. (d) Determine the mass-flow rate for a backpressure of 0 kPa.
