Unformatted text preview: 3-34E Left chamber of a partitioned system contains water at a specified state while the right chamber is evacuated. The partition is now ruptured and heat is transferred to the water. The pressure and the total internal energy at the final state are to be determined.AnalysisThe final specific volume is /lbmft5.1lbm2ft33322mVvAt this specific volume and the final temperature, the state is a saturated mixture, and the pressure is the saturation pressure 4E)-A(TableF300@sat 2psia67.03PPThe quality and internal energy at the final state are Btu/lbm38.460)25.830)(2299.(51.2692299./lbmft)01745.4663.6(/lbmft)01745.5.1(223322fgffgfuxuuxvvvThe total internal energy is then Btu920.8)Btu/lbm38.460)(lbm2(22muU3-35 The enthalpy of R-134a at a specified state is to be determined.
