Air enters an adiabatic compressor at 100 kPa (absolute) and 20ºC 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 70percent. Neglecting the changes in kinetic and potential energies,determine (a) the exit temperature of air and (b) the powerrequired to drive the compressor.
