A piston cylinder system contains compressed 5 kg of liquid water with a pressure of 500 kPa and a temperature of 100oC (state A). Under constant pressure of 500 kPa, this H2O is heated to saturated liquid (state B), saturated mixture of liquid and vapor with a quality of 0.2 (state C), saturated mixture of liquid and vapor with a quality of 0.9 (state D), saturated vapor (state E) and superheated vapor with a temperature of 500oC (state F). (6a). (4p) Present this process in schematic Tv and Pv diagrams with each state clearly marked on them. (6b). (4p) Find the specific volume at state C. (6c). (4p) Find the total internal energy at state E.
