A rigid cylinder of 1 m3 It has a filling system based on an elastic balloon connected by a pipeline with a valve. Initially, the balloon, which maintains a proportional relationship between its diameter and the internal pressure, it has saturated steam of water at 1 MPa and a volume of 5 m3 . In the filling process, the pressure in the balloon decreases halfway and the final temperature of both is 165 C. Determine the final pressure of the cylinder, the conditions in which the fluid is found inside the cylinder and the work made in the process.
