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.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
