Determine the entropy generation in the compression process

Question

Problem

In an actual refrigeration cycle using R-134a as the working fluid, the refrigerant flow rate is 0.05 kg/s. Vapor enters the compressor at 150 kPa, -10^oC (h₁ = 394.2 kJ/kg, s₁ = 1.739 kJ/kg K) and leaves at 1.2 MPa, 75^oC (h₂ = 454.2 kJ/kg, s₂= 1.805 kJ/kg K). The power input to the non-adiabatic compressor is measured and found be 2.4 kW. The refrigerant enters the expansion valve at 1.15 MPa, 40^oC (h = 256.4 kJ/kg) and leaves the evaporator at 160 kPa, -15^oC (h = 389.8 kJ/kg). Determine the entropy generation in the compression process, the refrigeration capacity, and the COP for this cycle.

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
