Apiston-cylinder device initially contains steam at 3.5 mpa, superheated by 5 oc. now steam loses heat to the surrounding and the piston moves down, hitting a set of stops, at which point the cylinder contains saturated liquid water. the cooling continues until the cylinder contains water at 200 oc. determine: a) the initial temperature b) the enthalpy change per unit mass of the steam by the time the piston first hits the stops. c) the final pressure and quality (if mixture)
