2.51 Steam in a piston-cylinder assembly undergoes a polytropic

process, with n = 2, from an initial state where p₁ = 3.45 MPa, v₁

0.106 m³/kg, u₁ = 3171.1 kJ/kg, to a final state where u₂ = 2303.9 kJ/kg.

During the process, there is a heat transfer from the steam of magnitude

361.76 kJ. The mass of steam is 0.54 kg. Neglecting changes in kinetic

and potential energy, determine the work, in kJ, and the final specific

volume, in m³/kg.
