A piston cylinder assembly initially contains 5 kg of water, a saturated liquid vapor mixture at a pressure of 100 kPa. 2 kg of water is in the liquid phase and the rest is in the vapor phase. In this state, the piston is on the stoppers. Then there is a heat transfer to water, the pressure rises and the piston starts to move when it is 150 kPa. Heat transfer continues until the total volume is twice the initial volume. According to this; a) Draw the T-v and Pv diagram of the process. b) Initial and final temperatures, c) The mass of water in the liquid phase when the piston starts to move upwards
