Determine the mass flow rate of air


Solve the below problem:

Q: Air enters a compressor at ambient conditions of 15 psia and 60°F with a low velocity and exits at 150 psia, 620°F, and 350 ft/s. The compressor is cooled by the ambient air at 60°F at a rate of 1500 Btu/min. The power input to the compressor is 400 hp. Determine

(a) The mass flow rate of air and

(b) The portion of the power input that is used just to overcome the irreversibilities.
