question

200 stg ft^3/min of ethane at 70°F (C_p = 13.3 Btu/lb-mol F, \gamma = specific heat ratio = 1.22) is compressed from 11 psia to 1,000 psia in a three stage reciprocating compressor of 85 percent mechanical efficiency. Cooling water is used in the intercoolers and aftercooler to bring the compressed gas to 70°F. If 20 gal/min of water is used in the coolers, determine the change in temperature of the water. Also determine the power required to drive the compressor.
