Question
In a fixed volume container of 0.1 m3, initially there is saturated water vapor at 130 oC. The vessel is
connected to a pipe through which steam flows through a valve at 2 MPa pressure and 350 oC
temperature. Then the valve opens and steam enters the container. Meanwhile, the temperature of
the steam in the container remains constant at 130 oC due to the heat transfer to the environment.
When it is observed that 3/4 of the water in the container covers the liquid phase by mass, the valve
is closed.
