rigid insulated tank =0.25 m x,= 1.0 P, - 200 kP V3=0.5 m² T, and P, v, - 0.25 m 17, =250°C P, - 1.0 MPa partition
Figure demonstrates a rigid, insulated tank that is divided into two parts by an interior partition. The volume below the partition is V1 = 0.25 m3 and contains water at T1 = 250°C and P1 = 1 MPa. The volume above the partition is V2 = 0.25 m3 and contains saturated water vapor at P2 = 200 kPa. At some time, the partition is ruptured allowing the water below the partition to mix with the water above the partition. Eventually, all of the water in the tank comes to new equilibrium at a uniform temperature T3 and P3. a) What is the final temperature and pressure in the tank, T3 (in °C) and P3 (in kPa)?
