Problem 3.052 a piston–cylinder assembly contains 2 lb of water, initially at 100 lbf/in.2 and 600°f. 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 300°f and the water is a two-phase liquid–vapor mixture with a quality of 40%. neglect kinetic and potential energy effects. determine the work and heat transfer for each process, all in btu.
