A nozzle receives 0.5 kg/s of air at a pressure of 2700 kPaa and a velocity of 30 m/s and with an enthalpy of 923.0 kJ/kg, and the air leaves at a pressure of 700 kPaa and with an enthalpy of 660.0 kJ/kg. Determine the exit velocity from the nozzle for a) adiabatic flow; and b) flow where the heat loss is 1.5 kJ/kg. [Ans. a) 725.88 m/s, b) 723.81 m/s]

Question
A nozzle receives 0.5 kg/s of air at a pressure of 2700 kPaa and a velocity of
30 m/s and with an enthalpy of 923.0 kJ/kg, and the air leaves at a pressure of
700 kPaa and with an enthalpy of 660.0 kJ/kg. Determine the exit velocity from the
nozzle for a) adiabatic flow; and b) flow where the heat loss is 1.5 kJ/kg.
