Assignment Help Mechanical Engineering

Air enters a compressor at 300 K and 100 kPa at a volumetric flow rate of 4 m3/s. The air is compressed such that the outlet temperature is 620 K.

Determine:

a) mass flow rate of air through the compressor (kg/s)

b) the change in specific enthalpy of the air from inlet to outlet

c) the power input to the compressor.
