A piston cylinder system stores 15 kg of water that is initially at 120 degrees Celsius, with 0.25 quality. A two step process occurs, such that the final state has a pressure of 300 KPa.
A)Calculate the change in internal energy [in KJ/kg] associated with process 1-2.B)What is the volume of the tank in [m^3] at state 1?C)What is the volume of the tank in [m^3] at state 3?D)What is the internal energy of the system at the final state?E)Sketch the processes on a Pv, Tv and a PT diagram. [Label the phases, states 1,2,3 and include isotherms.]
