1 kg of H 2 O is contained in a rigid, insulated cylindricalvessel. The H 2 O is initially saturated vapor at 120°C. The vessel is fitted with a paddle wheel from which a mass is suspended. As the mass descends a certain distance, the H 2 O is stirred until itattains a final equilibrium state at a pressure of 3 bar. The only significant changes in state areexperienced by the H 2 O and the suspended mass. Determine, in kJ,(a) the change in exergy of the H 2 O.(b) the change in exergy of the suspended mass.(c) the change in exergy of an isolated system of the vessel and pulley–mass assembly.(d) the destruction of exergy within the isolated system.
