In a frictionless piston-cylinder assembly shown in the figure, there is a liquid water-steam mixture of 20% quality at a pressure of 150 kPa at the beginning, and it is heated under constant pressure until the piston touches the stoppers. Then the heat transfer process is continued until all of the water is in the saturated vapor phase. The kinetic and potential energy changes are negligible. a) Calculate the amount of heat transferred to the system and the work done during this process in kJ/kg. b) In the last case, the pressure (kPa) and temperature of the water in the cylinder c) Show the process in the T-v diagram. (Note: initially the piston is ready to move)
