Question 2: In a steam power plant operatingaccording to the ideal intermediate superheated Rankine cycle,water vapor enters the high pressure turbine at 8 MPa pressure and500 oC temperature and expands to 3 MPa pressure. Then,the steam is re-heated to a temperature of 500 oC in theboiler and expands to 20 kPa condenser pressure in the low pressureturbine.
I. Show the cycle in the T-s diagram and explain for whatpurpose intermediate superheating is done.
II. Calculate the total turbine work.
III. Calculate the thermal efficiency of the cycle.
