Steam in a piston cylinder assembly undergoes a polytropic process with n=2 from an initial state of P=500 psi, v1=1.7 ft3/lb, u1 = 1363.3 Btu/lb to a final state u2 = 990.5 Btu/lb. There is also heat transfer from the steam during the process of magnittude 343 Btu. The mass of the steam is 1.2 lb, find the work in Btu and the specific volume in ft3/lb. Ignore the changes in the kinetic and the potential energies.
