a compressor operates at steady state. air enters the compressor with a mass flow rate of 28800 kg/h at .99 bar and 27C and exits at 7.5 bar. the compressor operates adiabatically and the effects of motion and gravity can be ignored. the compressor isentropic efficiency is 70%. for exergy analysis the reference state is To=27C Po=.99 bar. use ideal gas model for air (MW=28.97 kg/kmol)

a. determine required power for compressor in kW
b. determine rate of exergy destruction
c. determine the exergetic efficiency
