Sаturаted vаpоr R-410A enters the uninsulated cоmpressоr of a home central air-conditioning system at 5∘C (hi = 280.6 kJ/kg, si = 1.0272 kJ/kgK). The flow rate of refrigerant through the compressor is 0.08 kg/s, and the electrical power input is 3 kW. The exit state is 65∘C, 3000 kPa (he = 307.8 kJ/kg, se = 1.0140 kJ/kgK). Any heat transfer from the compressor is to the ambient environment at 30∘C. Determine the rate of entropy generation for this process. (10 pts) Hints: steady-state single flow, assume negligible change in kinetic and potential energies Please (1) do the calculations on paper, and (2) provide a numerical answer here.
