Which outcome affects the efficiency within an ideal ORC?

A)A small working fluid enthalpy jump
B)Minimal stages required within turbine
C)Using zeotropic mixtures with higher glide
D)High-pressure condenser subcooling requirements

💡 Explanation

A small enthalpy jump during evaporation reduces the thermodynamic efficiency because Rankine cycle efficiency directly correlates with the enthalpy change, therefore less heat transformed into work rather than other parameters due to operational cycle.
