Water in a piston-cylinder assembly undergoes two processes

Assignment Help Mechanical Engineering

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
