Assume that a supersonic converging-diverging nozzle operating isentropically delivers air to a receiver with pressure of 1175 kPa. The entrance conditions are 1500 kPa abs, 327 °C, and near-zero Mach number. Use the isentropic table only. (a) What is the exit Mach number? Mention the operation mode. (b) What is the exit temperature? (c) Determine the area ratio Ay/A2, As, and the mass flow rate if D-100 mm. (d) If the entire diverging portion of the nozzle were suddenly detached, what would the Mach number and rh /IA be at the new outlet? Pt Preceiver T
