**1. Homework Statement**

Steam in a piston-cylinder assembly undergoes a polytropic process, with n = 2. The initial state is p1 = 500lbf/in^2, v1 = 1.701 ft^3/lbm and u1 = 1363.3 BTU/lbm. IN the final state, u2 = 990,58 BTU/lbm. During the process, there is heat transfer from the steam of magnitude 342.9 BTU. THe mass of the steam is 1.2 lbm. Neglecting changes in kinetic and potential energies, calculate the work of the process, in BTU, and the final specific volume in ft^3/lbm.

**2. Homework Equations**

W=Q-dU

**3. The Attempt at a Solution**

So far all I can do is answer the first part of the question:

W = -342.9 BTU - m(u2-u1)

W = 104.4
