Steam in a piston-cylinder asembly undergoes a polytropic process, with n=2, from an initial state where p1=500 psi, v1=1.701 (ft^3)/lbm, u1=1363.3 Btu/lbm to a final state where u2=990.58 Btu/lbm. During the process, there is a heat transfer from the steam of magnitude 342.9 Btu. The mass of steam is 1.2 lbm. Neglecting changes in kinetic and potential energy, plot the process on a P-v diagram.
