Question

2.48 Steam in a piston-cylinder assembly undergoes a poly- tropic process, with n 2, from an initial state where p 3.45 MPa, v 0.106 m/kg, u 3,171.1 kJ/kg, to a final state where u 2,303.9 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 m'/kg.
