When a liquid flows through a control valve, the flow velocity at the throttle increases sharply and the pressure drops. If the pressure falls below the saturated vapor pressure of the liquid at that temperature, the liquid will vaporize; the resulting gas leads to two-way flow of both liquid and gas. This phenomenon is known as (A) A. Flashing B. Cavitation C. Erosion by cavitation D. Corrosion
