1.00 lbm of saturated water vapor at 212°F is condensed in a closed, nonrigid system to saturated liquid at 212°F in a constant pressure process by a heat transfer across a system boundary with a constant temperature of 80.0°F.
What is (a) the irreversibility and (b) the change in total availability for this process if the local environment is at 14.7 psia and 70.0°F?
