A Device Which makes Power Plant A True Cycle..
A Device Which set the limit on minimum cycle pressure…..
Volumes and temperatures are same.
As the air-steam mixture moves through the condenser and the steam is condensed, its temperature decreases owing to decreasing partial pressure of saturated steam.
This is due to increase in relative content of air in the mixture.
The pressure also decreases due to resistance to flow of steam.
The zone of intensive condensation.
The zone of cooling of air-steam mixture.
