4.47 A system consisting of 2 lb of water vapor, initially at 300°F and occupying a volume of 20 ft3, is compressed isothermally
to a volume of 9.05 ft3. The system is then heated at constant volume to a final pressure of 120 lbf/in.2 During the isothermal compression there is energy transfer by work of magnitude 90.8 Btu into the system. Kinetic and potential energy effects are negligible. Determine the heat transfer, in Btu, for each process.
