A heat pump with refrigerant-134a as the working fluid is used to keep a space at 258C by absorbing heat from geothermal water that enters the evaporator at 508C at a rate of 0.065 kg/s and leaves at 408C. The refrigerant enters the evaporator at 208C with a quality of 23 percent and leaves at the inlet pressure as saturated vapor. The refrigerant loses 300 W of heat to the surroundings as it flows through the compressor and the refrigerant leaves the compressor at 1.4 MPa at the same entropy as the inlet. Determine (
