Which outcome occurs when high-pressure liquid water flashes to steam in a turbine?

A)Erosion increases due to cavitation
B)Efficiency peaks because fluid superheats
C)Volumetric flow rate stabilizes
D)Backpressure decreases within inlet nozzle

💡 Explanation

Erosion rises because the rapid phase change causes vapor bubbles that collapse violently; this process is called cavitation. Therefore, erosion risk elevates, rather than stabilization or benefits because flow non-uniformity is intensified during cavitation inception.
