Solve the below problem:
Q: Two heavily insulated tanks are connected by a valve. Tank A contains 0.6 kg of water at 300 kPa 300?C. Tank B has a volume of 300 L and contains water at 600 kPa, 80% quality. The valve is opened, and the two tanks eventually come to a uniform state. Assuming the process to be adiabatic, show the final state (u, v) is two-phase and iterate on final pressure to match required internal energy.
