NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A 0.6-m3 rigid tank contains refrigerant-134a initially at 200 kPa and 40 percent quality. Heat is transferred now to the refrigerant from a source at 35°C until the pressure rises to 400 kPa.

4-31E A 20 ft³ rigid tank initially contains saturated refrigerant-134a vapor at 160 psia. As a result of heat transfer from the refrigerant, the pressure drops to 50 psia. Show the process on a P-v diagram with respect to saturation lines, and determine (a) the final temperature, (b) the amount of refrigerant that has condensed, and (c) the heat transfer.

! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A piston-cylinder device initially contains 1 kg saturated liquid water at 200°C. Now heat is transferred to the water until the volume quadruples and the cylinder contains saturated vapor only. The saturated liquid properties of water at 200°C 3 are vf= 0.001157 m³/kg and uf- 850.46 kJ/kg (Table A-4). Water mkg 200°C Q Determine the final temperature and pressure. (You must provide an answer before moving to the next part) The final temperature is The final pressure is °C. kPa.
