A steam power plant works between a boiler pressure of 40 bar and a condenser pressure of 0.04 bar. The turbine receives dry saturated steam that expands isentropically to the condenser pressure. Calculate the thermal efficiency, the work ratio and the specific steam consumption: a. For a Carnot cycle. b. For a Rankine cycle. Draw a T-s diagram for both cycles.

Q6:
A steam power plant works between a boiler pressure of 40 bar and a condenser pressure
of 0.04 bar. The turbine receives dry saturated steam that expands isentropically to the
condenser pressure. Calculate the thermal efficiency, the work ratio and the specific
steam consumption:
a. For a Carnot cycle.
b. For a Rankine cycle.
Draw a T-s diagram for both cycles.
(Ans: 0.423, 0.746, 4.82 kg/kWh, 0.363, 0.996, 3.7 kg/kWh)
