Steam undergoes an isentalpic (h=C) process from 1.5 mpa, 350°c to 10 mpa. Find the final temperature using the mollier charter

A piston/cylinder has a water volume separated in VA = 0.3 m³ and VB = 0.4 m by a stiff membrane. The initial state in A is 1000 kPa, x = 0.8 and in B it is 1500 kPa and 250°C. Now the membrane ruptures and the water comes to a uniform state at 200°C. What is the final pressure? Find the work and the heat transfer in the process. Po mp cb A:H2O B:H20
