Frictionless piston-cylinder contains 0.10 kg of saturated water vapor maintained at a constant p = 6.0 bar. heat transfer occurs from the fluid to the atmosphere until the water is saturated liquid. determine a) work done by the surroundings on the water vapor system. b) the useful wok done on the water vapor (removing work done by the atmosphere) c) the heat transfer from the water vapor. d) the maximum useful work that could be extracted in going from the initial to the final state. To = 295 k and Po = 1 bar.
