2. Cavitation
   The formation and collapse of gas pockets or bubbles on the blade of an impeller or the gate of a valve; collapse of these pockets or bubbles drives water with such force that it can cause pitting of the gate or valve surface.

4. cavitation
   the formation and collapse of vapor- or gas-filled cavities that result from a sudden decrease and increase of pressure. Cavitation can cause mechanical damage to adjacent surfaces in meters, valves, pumps, and pipes at locations where flowing liquid encounters a restriction or change in direction.

5. Cavitation
   A condition which can occur in liquid handling machinery (e.g. centrifugal pumps) where a system pressure decrease in the suction line and pump inlet lowers fluid pressure and vaporization occurs. The result is mixed flow which may produce vibration and damage to components.Cavitation can occur in a...

6. Cavitation
   A condition of liquid flow where a liquid vaporises and the vapour bubbles subsequently collapse. Can produce surface damage to pumps; valves etc.

7. cavitation
   The formation and instantaneous collapse of innumerable tiny voids or cavities within a liquid subjected to rapid and intense pressure changes. Cavitation produced by ultrasonic radiation is sometimes used to effect violent localized agitation. Cavitation caused by severe turbulent flow often leads to cavitation damage.

    [bone] Cavitations are an area of dead bone caused by a dearth of blood flow to that part of the bone. A cavitation is a hole in the blood vessel that cannot be visually detected with the naked eye. Jawbone cavitations, also called neuralgia inducing osteonecrosis (NICO), are extraction sites in the tooth that have not healed. ...
