1. Rankine cycle operates between condenser pressure of 0.1 bar and boiler pressure of 70 bar. a) Suggest a suitable temperature at the turbine inlet and explain your suggestion. Consider a range 250-450C. [5 Marks] b) Based on the temperature suggested in part (a), assuming turbine efficiency of 90%, calculate the net work and the thermal efficiency of the cycle. [15 Marks] c) How can you improve the cycle efficiency by changing the boiler pressure? How would this affect the net power and the moisture content at the turbine outlet? Closeks]
