A piston/cylinder has a water volume separated in V_A = 0.2 m³ and V_B = 0.3 m³ by a stiff membrane similar to the one in Fig. P6.128. The initial state in A is 1000 kPa, x = 0.75, and in B it is 1600 kPa and 250◦C. Now the membrane ruptures and the water comes to a uniform state at 200◦C with heat from a 250◦C source. Find the work, the heat transfer, and the total entropy generation in the process.
