Problem 05.042 Nozzle flow
Air enters an adiabatic nozzle steadily at 300 kPa, 200°C, and 45 m/s and leaves at 110.0 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 1.02 kJ/kg. C.
