A 2-m3 rigid insulated tank initially containing saturated water vapor at 1 MPa is connected through a valve to a supply line that carries steam at 400°C. 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 300°C. Determine the mass of the steam that has entered and the pressure of the steam in the supply line. The initial and final properties of steam in the tank are v1 = 0.19436 m3/kg, u1 = 2582.8 kJ/kg, v2 = 0.12551 m3/kg, and u2 = 2773.2 kJ/kg. Solve using appropriate software.
The mass of the steam is kg.
The pressure of the steam is kPa.
