b) Air enters a converging-diverging nozzle at 900 kPa and 427 °C with negligible velocity. The mass flow rate through the nozzle is 3 kg/s and the Mach number at the exit is 2. Determine: i) the velocity, static pressure, static density and the area at the exit, and ii) the area at the throat. Properties of Air: k = 1.4 R= 287 J/kg K and Cp = 1005 J/kg K
