Consider a piston-cylinder assembly containing 10 kg of saturated liquid water at 1.5 bar. The assembly is placed on a hot plate. Heat transfer occurs slowly from the hot plate to the water from the bottom surface of the cylinder, and the pressure of the water remains constant as the phase change occurs. The process continues until a quality of 80% is reached. There is no heat transfer from any other cylinder surface or to the piston. Additionally, the kinetic and potential energy effects are negligible. a) For the water as the system, determine the work and heat transfer, each in KJ. b) Consider an enlarged system that includes the water and the bottom surface of the piston-cylinder assembly, which is in contact with the hot plate, such that the boundary temperature is 120 °C. Neglecting any change of state of the cylinder bottom surface material, calculate the entropy production for the enlarged system, in kJ/K. c) Represent the process on T-s and P-v diagrams.
