A piston-cylinder assembly contains 2 lb of water initially at 100 lbf/in and 400F. The water undergoes two processes in series: a constant-pressure process followed by a constant -volume process. At the end of the constant-volume process, the temperature is 300F and the water is a two-phase liquid-vapor mixture with a quality of 60%. Neglect kinetic and potential energy effects. a) Sketch T-v diagram b) Sketch p-v diagram c) Label states with their p, v, and T values d) Identify where work is done on or by the system on the diagram. Indicate whether it is done on or by the system. e) Determine the work and heat transfer for each process in Btu.
