Discussion:
Power required to drive the compressor
Provide step by step calculations.
Q: Air enters a steady-flow compressor with a specific enthalpy of 293.4 kJ/kg and a velocity of 60m/s, and leaves with a specific enthalpy of 343 kJ/kg and a velocity of 120m/s. The mass flow rate of the air is 1kg/s, and the heat transfer rate from the air to the surroundings is 19kJ/s. Calculate the power required to drive the compressor. Assume the change of potential energy is negligible.
