Consider a steam turbine operating sub-optimally if liquid water enters alongside steam, which consequence results from droplet formation?

A)Erosion increases due to cavitation
B)Blade fatigue strengthens, resonance minimized
C)Turbine efficiency increases markedly overall
D)Heat transfer rises in the stator

💡 Explanation

Erosion increases because cavitation undergoes inception due to rapid boiling and collapsing vapor bubbles causing pitting damage; therefore, efficiency drops and damage accelerates, rather than uniform wear or better heat transfer, which would require other conditions.
