Unformatted text preview: #4 (4-60) Calculate the change in enthalpy of argon, in kJ/kg, when it is cooled from 400 C to 100C. If neon had undergone this same change of temperature, would its enthalpy change have been any different? #5 (5-119) Refrigerant 134a enters the condenser of a refrigerator at 1200 kPa and 80 C, and leaves as a saturated liquid at the same pressure. Determine the heat transfer from the refrigerant per unit mass. #6 (5-123) An insulated rigid tank is initially evacuated. A valve is opened, and atmospheric air at 95 kPa and 17 C enters the tank until the pressure in the tank reaches 95 kPa, at which point the valve is closed. Determine the final temperature of the air in the tank. Assume constant specific heats....
