Air enters an adiabatic compressor at 100 kPa (absolute) and 20 ºC at a rate of 0.075 m3 /s, and it exits at a pressure of 900 kPa (absolute). The compressor has an isentropic efficiency of 70 percent. Neglecting the changes in kinetic and potential energies, determine (a) the exit temperature of air and (b) the power required to drive the compressor.
