To produce more power the upper management decided to modify the power plant by placing the stage
2 as a saturated liquid stage. The condenser site was planned to leave as it is with the same parameters.
The flow rates stays the same. See the figure below for the data. Again, this an ideal case: S2-S1; S3=54.
