Rigid tank A and tank B (containing water) are connected to a piston cylinder with two valves as shown below. The piston cylinder assembly is initially (state 1) empty when the valves are closed.
The pressure required to float the piston is 800kPa, the piston is constantly loaded and is free to move. Now the valves are opened and the fluid reaches a uniform state at 250C within the system (state 2).
Determine: (a) The final volume (5 points) (b) The final pressure (5 points) (c) The work done (5 points) (d) Show the process on a PV diagram (5 points) (e) The heat transfer
The initial conditions for tank A are: Mass=3kg T=120C Volume=0.6?3 The initial conditions for tank B are: P=600kPa T=200C Volume=0.4?3
