Question Completion Status: QUESTION 1 20 points Save Ans The heat-pump system shown is designed to provide water-heating and space-cooling. The system includes a heat exchanger to subcool the R134a refrigerant at the outlet of the water heater while heating the refrigerant at the outlet of the evaporator. Given the following data, determine the enthalpy at each station, 1 through 6, using the R134a property tables (click here). Type your answers...

174 2 combustor , =1500 K Problem 2 (22 pts): Brayton cycle and entropy calculations An open Brayton cycle is used to generate electricity. Air enters the isentropic compressor at T1 = 300 K and P1 = 100 kPa with a mass flow rate m = 1.5 kg/s. The combustor can be modeled as a constant-pressure heat exchanger, supplying 1540 kW of thermal power to the air from a thermal reservoir (Th = 1750 K). Air enters the isentropic turbine...
