A vapor compression refrigeration cycle utilizes R-134a as the working fluid. The refrigerant flow rate is 50 g/s. Vapor at 150 kPa and -10 0C enters the compressor and leaves at 1.2 MPa and 75 0C. The power input to the non-adiabatic compressor is measured and found to be 2.4 kW. The refrigerant enters the expansion valve at 1.15 MPa and 40 0C and leaves the evaporator at 160 kPa and -15 0C. Determine the entropy generation in the compression...

Tubular heat exchanger design A liquid food (with specific heat 3.9 kJ/[kg °C]) flows in the inner pipe of a double pipe heat exchanger. The liquid food enters the heat exchanger at 72°C and exits at 6°C at a flow rate of 0.5 kg/s. In the annular section, cold water at 2°C enters the heat exchanger and flows concurrently at a flow rate of 12 kg/s. The average specific heat of water is 4.10 kJ/(kg °C). Assuming steady-state conditions. a)...
