Which outcome occurs within a geothermal power plant's turbine when the working fluid has incomplete isobaric phase change?

A)Reduced overall cycle thermal efficiency
B)Increased turbine blade fatigue rate
C)Elevated risk of stator winding arcing
D)Depleted available pressure head

💡 Explanation

Reduced cycle efficiency results because using wet steam forces the isentropic enthalpy change on the turbine outlet fluid in the Rankine thermodynamic cycle to deviate from theoretical limits; therefore the Carnot efficiency decreases rather than only pressure or component lifecycle limitations alone, assuming a given heat input.
