Which mechanism initiates cavitation in a high-speed pump?

💡 Explanation

Cavitation begins with vapor pressure decreasing below the fluid's saturation point; therefore, bubbles form because of rapid pressure drop. This vaporisation is driven by the Bernoulli effect, forming vapour cavities, rather than solely by increased turbulence.
