← ScienceWhich outcome occurs from cavitation risk in hydraulic turbines modeled using the Bernoulli equation?
A)Turbine blade material erodes rapidly✓
B)Increased laminar flow near surfaces
C)Elevation of the turbine efficiency
D)Pressure increases the velocity decrease
💡 Explanation
Vapor bubbles from cavitation collapse violently on turbine blades, because localized low pressure forms during increased flow from the Venturi effect; therefore, material erodes, rather than efficiency improvements or simple pressure increases, at the points predicted by the equation.
