Cavitation is a phenomenon whereby liquid flowing through a
a valve or pump under reduced pressure(below vapour
pressure)will form gaseous bubbles that will collapse upon
pressure recovery prodcing potential damage to the valve or
pump internals leading to premature failure .Ie the
pressure drops below the vapour pressure leading to
formation of vapour bubbles and tries to increase above the
vapour pressure.This is sserious concern in high pressure
drop applications.
