← ScienceWhich consequence results when rapid vapor condensation occurs in a turbine?
A)Erosion via cavitation accelerates rapidly✓
B)Increased blade lubricating film thickness
C)Improved thermal energy displacement cycle efficiency
D)Decreased pressure upon the turbine casing
💡 Explanation
Erosion due to cavitation accelerates because vapor bubble collapse undergoes rapid implosion which generates shockwaves against turbine blades. Therefore cavitation erosion happens, rather than lubrication (which mitigates erosion), increased efficiency, or decreased casing pressure, which affect the entire cycle.
