Phase Transition Example A container having a volume of 2 m3 contains .05 m3 of saturated liquid water and 1.95 m3 of saturated vapor at 0.15 MPa. (a) Determine the amount of heat transfer in order to vaporize all the liquid water in the container. (b) What is the final pressure (at the saturated vapor condition). (c ) What is the quality at the initial state. (Neglect losses) vapor liquid

Phase Transition Example (cont.) Saturated vapor line Constant pressure line P=0.15 MPa 2 Saturated liquid line Transition from 1: a mixture of liquid and vapor to 2: 100% saturated vapor. It should follow the green line since the volume and the mass both are constants during this process. 1 V
