A rigid tank A of volume 0.6 m3 contains 3 kg of water at 120?C, and rigid tank B has a volume of 0.4 m3 with water at 600 kPa, 200?C. The tanks are connected to a piston/cylinder initially empty with closed valves as shown in Fig. P3.217. The pressure in the cylinder should be 800 kPa to float the piston. Now the valves are slowly opened and heat is transferred so that the water reaches a uniform state at 250?C with the valves open. Find the final volume and pressure, and the work and heat transfer in the process.
