Aconvergent-divergent nozzle is designed to expand air from a chamber in which the pressure is 700 kpa and the temperature is 35°c to give mach 1.6. the mass flow rate through the nozzle under design conditions is 0.012 kg/s. find
a. the throat and exit areas of the nozzle
b. the design back-pressure and the temperature of the air leaving the nozzle with this back-pressure nozzle
c. the lowest back-pressure for which there will be no supersonic flow in the
d. the back-pressure below which there are no shock waves in the nozzle
