Question

Nitrogen gas at 135 kPa and 29 C enters an adiabatic nozzle steadily with a velocity of 130 m/s and leaves at 78 kPa and 18 C. The molar mass of nitrogen is M = 28 kg/kmol and the enthalpies are 8541 kJ/kmol at 18 C and 8723 kJ/kmol at 29 C. a. Write down the energy balance equation. b. Determine the exit velocity c. The ratio of the inlet to exit area A1/A2.

Answer 1
