Methane gas is compressed at the rate of 3x104 m3/hr (as measured at 0.1013 MPa and 15C) from 0.69 MPa and 26.7C to 3.45 MPa. The compressor operates adiabatically and has an efficiency of 80%. After compression, the methane is colled at a constant pressure of 3.45 MPa to a temperature of 38C.
What is the power requirement of the compressor?
