Consider a rigid vessel. It contains 1Okg of water at 4MPa and 450 degree C. The vessel is cooled slowly until water exists as saturated vapor. Calculate the pressure in the final state in kPa.

Solution

Phase is changing from superheated state to saturated state which will occur at constant pressure so final pressure is 4Mpa as initial
