Task 3 Water is initially at 3 MPa and 300 C (state 1) contained within a piston cylinder device. The Water is cooled at constant volume until it reaches a temperature of 200 C (State 2). The water is then compressed to a state where the pressure is 2.5 MPa (State 3). Sketch the T-V diagram to show the three states and determine the properties at all described states in the table below and the quality where appropriate.

Q/ A radiator of steam heating system has a volume of 0.2 m'. When the radiator is filled with saturated steam at a pressure of 1.5 bar all valves are closed. After a period of time the pressure inside the radiator becomes 1.4 bar due to heat lost to surrounding air. Calculate: 1- mass of steam within the radiator. 2- mass and volume of liquid water at the final state. 3- mass and volume of vapor at the final state. From steam tables, at 1.5 bar, Since all valves are closed the specific volume of steam remains constant as heat is lost. At 1.4 bar, Since v2 < v g at 1.4 bar the steam becomes wet.
A piston cylinder device with stops as shown contains water initially at 25 C and 100 kPa "State 1".
