A converging-diverging nozzle is supplied with air from a reservoir where the pressure and temperature are 600 kN/m² and 18°C respectively. The throat area is 10 cm² and the nozzle is designed for a final Mach number of 2.0. The flow is isentropic and the air behaves as an ideal gas. Calculate: a) The exit plane area and the exit plane pressure at the given design condition. b) The pressure at the throat when the nozzle first chokes and the corresponding throat temperature. c) The density of the fluid in the reservoir. d) The density of the fluid at the throat. e) The choking mass flow. f) The maximum exit pressure for which the nozzle remains choked.
