A sealed, rigid kitchen pressure cooker with a volume of 1.00 ft3 contains 2.20 lbm of a mixture of liquid plus vapor water at 14.7 psia. The pressure cooker is then heated until its internal pressure reaches 20.0 psia.
Determine (a) the heat transfer during the process, (b) the irreversibility of the process if the inner surface of the pressure cooker is constant at 250.°F, and (c) the change in total availability of the water if the local environment is at 14.7 psia and 70.0°F.
