Steam in a piston-cylinder assembly undergoes a polytropic process, with n = 2, from an initial state where V₁ = 1.75440 ft³, p₁ = 450lb/in², and u₁ = 1322.4 Btu/lb to a final state where u₂ = 1036.0 Btu/lb and v₂ = 3.393 ft3/lb. The mass of the steam is 1.0 lb. Changesin kinetic and potential energy can be neglected.Determine the change in volume, in ft3, the energy transfer by work, in Btu, and the energy transfer by heat, in Btu.

A vapor compression refrigeration cycle uses steam as the working fluid. Steamflows steadily with a mass ow rate of 0.5 kg/s. Saturated vapor at 2.0 o C (State 1) enters an uninsulated compressor and it is compressed to 0.35 bar (State 2). Heat transfer at the rate of 105 kJ/s occurs from the compressor to its surroundings and the heat transfer exactly balances the entropy generation rate so that s2 = s1. The boundary and surrounding temperature of the compressor is measured to be 26.67 o C. Steam exits as saturated liquid at 0.34 bar (State 3) from the condenser. Steam leaving the condenser is then throttled in an expansion valve (State 4) before entering a constant pressure evaporator to complete the thermodynamic cycle.
