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