Referring to the figure shown below, water contained in a piston–cylinder assembly, initially at 1.5 bar and a quality of 60%, is heated at constant pressure until the piston hits the stops. Heating then continues until the water is saturated vapor. The initial height, L1, is 0.05 m and the change in height, L2, is 0.03 m. For the overall process of the water, evaluate the work and heat transfer, each in kJ/kg. Kinetic and potential effects are negligible.
Question 1 A piston-cylinder assembly contains 3.2 kg of water at 211.9oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 51.5 bar. During compression, there is a heat transfer of energy from the water to its surroundings having a magnitude of 230 kJ. Neglecting changes in kinetic energy and potential energy, determine the work, in kJ, for the process of the water. Question 2 Water, initially saturated vapor at 10.2 bar, fills...
