Carnot Efficiency vs Rankine Efficiency

[mm391]

Hi,

Given value of top and bottom temperatures can anyone explain why the Ideal Carnot Cycle is more efficient than the Rankine cycle but why the Rankine is the preferred model? I know that in the Carnot the pump would have to be able to deal with a mixture of steam and water and the turbine would have to be able to deal with wet steam (which is obviously not good).

Thanks

The Rankine cycle is practicable for the same reasons you stated.

Carnot cycle also assumes a 100% isentropic turbine, which is not achievable in reality.
