Convergent divergent nozzle is designed to expand air at air from chamber in which the pressure is 800 kpa and the temperature is 40 c to give mach no 2.5 the throat are for the nozzle is .0025 m^{2} 1- The flow rate through the nozzle under design conditions
2- The exit area of the nozzle
3- The design back-pressure and the temperature of air leaving nozzle with this back pressure
4-The lowest back-pressure for which there is only subsonic flow in the nozzle
5- The back-pressure at which there is a normal shock wave on the exit plane of nozzle
6- The back-pressure below which there are no shock waves in the nozzle
7-The range of back-pressures over which there are oblique shock waves in the exhaust from the nozzle
8- The range of back-pressures over which there are expansion waves in the exhaust from the nozzle
9- The back-pressure at which a normal shock wave occurs in the divergent section of the nozzle at a point where the nozzle area is half way between throat and exit plane the throat and exit plane areas.
