Water initially at 200 kPa and 300°C is contained in a pistoncylinder device fitted with stops. The water is allowed to cool at constant pressure until it exists as a saturated vapor and the piston rests on the stops. Then the water continues to cool until the pressure is 100 kPa.
1. On the T-v diagrams sketch, with respect to the saturation lines, the process curves passing through both the initial, intermediate, and final states of the water. Label the T, P and v values for end states on the process curves.
2. Find the overall change in internal energy between the initial and final states per unit mass of water.
