Which 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.
