Consider a simple ideal Rankine cycle with a fixed condenser pressure. If the boiler pressure is raised while the turbine inlet temperature is held constant, (select the correct statement)
A)the turbine work output will decrease.
B)the amount of heat rejected will increase.
C)the cycle efficiency will decrease.
D)the moisture content at turbine exit will increase.
E)the pump work input will decrease.

Question

Quizplus · Accepted Answer

Raising the boiler pressure while keeping the turbine inlet temperature constant increases the moisture content at the turbine exit, as the expansion process in the turbine ends at a lower quality.
