Water contained in a piston-cylinder assembly undergoes two processes in series from an initial state were the pressure is 10 bar and the temperature is 400°C.
Process 1-2: The water is cooled as it is compressed at a constant pressure of 10 bar to the saturated vapor state.
Process 2-3: The water is cooled at constant volume to 150°C.
Sketch both processes on T-v and p-v diagrams.
