A piston-cylinder assembly containing water, initially a liquid at 50 ?F, undergoes a
process at a constant pressure of 20 lbf/in2
to a final state where the water is a vapor at
300 ?F. Kinetic and potential energy affects are negligible. Determine the work and heat
transfer, in Btu/lb, for each of three parts of the overall process
(a) From the initial liquid state to saturated liquid state,
(b) From saturated liquid to saturated vapor and
(c) From saturated vapor to final vapor state, all at 20 lbf/in2
