MEEN 315-501 HW 04 1)A 9-m3container is filled with 300 kg of R-134a at 10℃. What is the specific enthalpy of the R-134a in the container? 2)Refrigerant-134a at 200kPa and 25℃flows through a refrigeration line. Determine its specific volume. 3)One pound-mass of water fills a container whose volume is 2 ft3. The pressure in the container is 100 psia. Calculate the total internal energy and enthalpy in the container. 4)2-lbm of water at 500 pisa initially fill the 1.5-ft3left chamber of a partitioned system. The right chamber’s volume is also 1.5 ft3, and it is initially evacuated. The partition is now ruptured and heat is transferred to the water until its temperature is 200°F. Determine the final pressure of water, in psia, and the total internal energy, in BTU, at the final state. 5)Under what conditions is the ideal-gas assumption suitable for real gases? And what is the difference between R and Ru? How are these two related?
