Question

Air enters an adiabatic nozzle steadily at 300 kPa, 200°C, and 45 m/s and leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 110 cm². The gas constant of air is 0.287 kPa.m³/kg.K. The specific heat of air at the anticipated average temperature of 450 K is Cp=102 kJ/kg.°C. Determine the exit temperature of the air.
