A steady flow, steady state air compressor handles 4000. ft3 /min measured at the intake state of 14.1 psia, 30.0°F and a velocity of 70.0 ft/s. The discharge is at 45.0 psia and has a velocity of 280. ft/s. Both the inlet and exit stations are located 4.00 ft above the floor.
Using the specific flow availability relative to the local environmental (ground state) temperature of 80.0°F and a pressure of 14.7 psia, determine
a. The discharge temperature and the power required to drive the compressor if the process is reversible and adiabatic.
b. The discharge temperature and the power required to drive the compressor if the process is irreversible and adiabatic with a compressor work transport efficiency of 80.0%.
