Problem 4 (20 pts; Show your work for partial credits) Air as an ideal gas flows through the compressor and heat exchanger as shown in the figure. A separate liquid water stream also flows through the heat exchanger. The data given are for operation at steady state. Stray heat transfer to the surroundings can be neglected, as can all kinetic and potential energy changes. Determine: (a) The compressor power, in kW, and the mass flow rate of the cooling water, in kg/s, and (b) The rates of entropy production, each in kW/K. for compressor and heat exchanger
