Consider a simple ideal Rankine cycle with fixed boiler and condenser pressures. If the steam is superheated to a higher temperature, explain if it is true that: the turbine work output will decrease. the amount of heat rejected will decrease. the cycle efficiency will decrease. the moisture content at turbine exit will decrease. the amount of heat input will decrease.

Solution

The moisture content at turbine exit will decrease is the correct statement.

When steam condenses inside a turbine, you lose efficiency and work potential. Superheated steam is very dry; there is very little chance for condensation now. Here the amount of heat input will increase.Work output increases. Heat rejection will increase. Moisture content will decrease.
