Apiston-cylinder contains 1.2 kg of saturated (vapor) steam at 200°c. heat is transferred to the steam, expanding it reversibly and isothermally to a pressure of 800 kpa assuming real properties (and using ees) determine: ? ? (a) the total amount of heat transferred in (kj) [218k/] (b)the total work done by the process (kj) [175.4 kj] where h2o= 200°c sat. vapor t= const
