Question 27

Cavitation is best prevented by avoiding conditions that allow the absolute pressure to fall below the ___________ of the liquid or by changing the material properties.

    Correct Answer: D

    Cavitation is best prevented by avoiding conditions that allow the absolute pressure to fall below the vapor pressure of the liquid. When the pressure drops below the vapor pressure, the liquid starts to form vapor bubbles, which can collapse and cause damage. Therefore, maintaining the pressure above the vapor pressure is crucial in preventing cavitation.
