Air is kept at a pressure of 10 bar and temperature of 300°C in a large vessel. A valve is suddenly opened and the air exits through a converging-diverging nozzle to a pressure of 1 bar. Assuming frictionless adiabatic flow, for a desired flow rate of 1 kg/s of the air, calculate the Mach number at the exit of the nozzle, the velocity at the exit of the nozzle, and the required cross-sectional area at the throat.
