A compressor is takes in air at an inlet pressure of P1 = 80 kPa and an inlet temperature of T1 = 20oC and exhausts it at an outlet pressure of P2 =800 kPa and an outlet temperature of T1 = 200oC. Air flows through the compressor at a mass flow rate of m = 1 kg/s. Assume that the compressor is adiabatic. Find the power required to run the compressor. (Your answer will be in kW.)
