The 2nd Law of Thermodynamics Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at 0.16 MPa, and leavesas superheated vapor at 0.9 MPa and 70◦C at a rate of 0.08 kg/s. Determine the rates of energy transfers bymass into and out of the compressor. Assume the kinetic and potential energies are negligible.

2nd Law of Thermodynamics Water enters the tubes of a cold plate at 65◦C with an average velocity of 50 ft/min and leaves at 110◦F. Thediameter of the tubes is 0.2 in. Assuming 20 percent of the heat generated is dissipated from the componentsto the surroundings by convection and radiation, and the remaining 80 percent is removed by the coolingwater, determine the amount of heat generated by the electronic devices mounted on the cold plate.

The 2nd Law of Thermodynamics Refrigerant-134a enters a diffuser steadily as saturated vapor 500 kPa with a velocity of 170 m/s, and it leavesat 600 kPa and 50◦C. the refrigerant is gaining heat at a rate of 2.5 kJ/s as it passes through the diffuser. Ifthe exit area is 75 percent greater than the inlet area, determine (a) the exit velocity (b) the mass flow rate of the refrigerant.
