As the resident thermal engineer at a new company developing inventive new ideas, you are faced with a scenario where 1.00 lbm of saturated water vapor at 212°F is condensed inside a flexible balloon to saturated liquid at 212°F.
This occurs in a constant pressure process by a heat transfer from the balloon to the environment. The balloon has an average surface temperature during this process of 125°F.
Determine the irreversibility and the change in total availability for this process if the local environment is at 14.7 psia and 70.0°F. Write and solve a thermodynamics problem that provides the answers to these questions.
