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

Question

Quizplus · Accepted Answer

Reheating in a Rankine cycle increases the average temperature at which heat is added, which increases the thermal efficiency. However, it also increases the amount of heat rejected because the steam exits the turbine at a higher temperature and pressure, leading to more heat being rejected in the condenser.
