Carbon dioxide gas enters a water-coded compressor at conditions P1 = 15(psia) and T1 = 50(oF). and is discharged at condition P2 = 520(psia) and T2 = 200(oF). The entering CO2 flows through a 4-inch-diamcter pipe with a velocity of 20(ft)(s)-1, and is discharged through a I-inch-diameter pipe. The shaft work supplied to the compressor is 5.360(Btu)(mol)-1. What is the heat-transfer rate from the compressor in (Btu)(hr)-1?
