A piston–cylinder device contains 5 kg of steam at 100°C with a quality of 50 percent. This steam undergoes two processes as follows: (1-2) Heat is transferred to the steam in a reversible manner while the temperature is held constant until the steam exists as a saturated vapor.(2-3) The steam expands in an adiabatic, reversible process until the pressure is 15 kPa. Sketch these processes with respect to the saturation lines on a single TS diagram and determine the heat transferred to the steam and work done by the steam.

(answer: 5641 kJ, 1291 kJ by saying "by the steam" we suggest magnitude of the work)
