2. 1’ , 1 and 1’’ are the state of the water.
• State 1 indicates the dry saturated steam
• State 1’ indicates wet steam
• State 1’’ indicates the superheated steam

3. In turbine Steam expands reversibly and adiabetically
to state 2 or to 2’ or to 2" as is the case.

4. In condenser, steam condenses reversibly at constant
pressure to water from state 2
( or 2’ or 2") to state 3.

5. Water at state 3 is then pumped to Boiler reversibly
and adiabetically at state 4.

6. In Boiler water is heated and converted to steam at
state 1 ( or 1’ or 1").
