Water in a piston-cylinder assembly undergoes two processes in series from an initial state where the pressure is 1.0 MPa and 400C.
Process 1-2: The water is cooled as it is compressed at constant pressure to the saturated vapor at 10bars.
Process2-3: The water is cooled at a constant volume to 150C
A: Sketch both processed on a T-v ad P-v diagram
B: For the overall process determine the work in kj/kg
C: For the overall process determine the heat transfer in kj/kg
