on An evacuated tank will be filled with steam that flows into the tank from a steam supply line where the pressure is 1.2 MPa and the temperature is 300 C. The steam from the supply line passes through a valve before it enters the tank. When the valve is opened, the tank fills with steam and the pressure increases until it reaches 2.0 MPa. At this point, steam flow stops and the valve is closed. If the heat lost from the system during the process is 80 KJ/kg and changes in kinetic and potential energies are negligible, using thermodynamic tables determine the final temperature of the steam in the tank.
