A piston–cylinder assembly contains 2 lb of water, initially at100 lbf/in.2 and 600°F. The water undergoes two processes inseries: a constant-pressure process followed by a constant volumeprocess. At the end of the constant-volume process, the temperatureis 300°F and the water is a two-phase liquid–vapor mixture with aquality of 50%. Neglect kinetic and potential energy effects.Determine the work and heat transfer for each process, all inBtu.
