Carbon dioxide gas enters a water-cooled compressor at conditions P1 = 1 bar and T1 = 10 °C, and is discharged at conditions P2 = 36 bar and T2 = 90 °C. The entering CO2 flows through a 10-cm-diameter pipe with an average velocity of 10 m⋅s−1, and is discharged through a 3-cm-diameter pipe. The power supplied to the compressor is 12.5 kJ.mol−1. What is the heat-transfer rate from the compressor?
