Thermodynamics
Air at a rate of 50 m3/min enters an adiabatic compressor at a pressure of 100 kPa and a temperature of 24.3 C and exits at 500 kPa and 189.55 C. It then enters an insulated heat exchanger where it gets cooled by water. The air exits the heat exchanger at a temperature of 57.35 C. Water enters the heat exchanger at 20 C and exits at 50 C. Calculate the compressor power in kW, the mass for rate of the cooling water in kg/sec, and the rate of entropy generation for the compressor and the heat exchanger. Assume a mean heat capacity of water at ?? = 4.18 ??/???. You may also assume that there is no pressure drop in the heat exchanger)
