A 2-m³ insulated tank initially containing saturated water vapor at 1 MPa is connected through a valve to a supply line that carries steam at 400 kPa. Now the valve is opened, and steam is allowed to flow slowly into the tank until the pressure in the tank rises to 2 MPa. At this instant the tank temperature is measured to be 450°C. (a) Determine the mass of the steam that has entered and the temperature of the steam in the supply line, and (b) If the tank was initially evacuated while everything else was kept the same, what would be the temperature of the steam in the supply line?

Question
A 2-m³ insulated tank initially containing saturated water vapor at 1 MPa is connected through a valve to a
supply line that carries steam at 400 kPa. Now the valve is opened, and steam is allowed to flow slowly into
the tank until the pressure in the tank rises to 2 MPa. At this instant the tank temperature is measured to be
450°C. (a) Determine the mass of the steam that has entered and the temperature of the steam in the supply
line, and (b) If the tank was initially evacuated while everything else was kept the same, what would be the
temperature of the steam in the supply line?
