Q2) Air (Y=1.4 and R=287 J/kg.k) flow through a converging - diverging nozzle designed to operate isentropically with supersonic flow at exit. The inlet and throat diameters of the nozzle are 43 mm and 25 mm respectively. The inlet pressure and temperature are 86 kpa and 298 k respectively and the back pressure (pressure at the exit section of the nozzle) is 12 kpa. What should be the exit diameter of the nozzle which corresponds to the maximum obtainable value of the Mach number? What are the mass flow rate of the air and its exit temperature. Find also the range of back pressure over which the nozzle is chocked.
