Question:

Two rigid tanks are filled with water (Fig. P3.214). Tank A is 0.2 m³ at 100 kPa, 150◦C and tank B is 0.3 m³ at saturated vapor of 300 kPa. The tanks are connected by a pipe with a closed valve. We open the valve and let all the water come to a single uniform state while we transfer enough heat to have a final pressure of 300 kPa. Give the two property values that determine the final state and find the heat transfer.
