"Cavitation may be encountered in many scientific fields. Mechanical and civil engineers are concerned with the prevention of cavitation erosion in the design of turbines, propellers, underwater missiles, and similar structures. Biologists and physiologists are seeking more knowledge concerning the tensile strength of liquids, such as, tree sap and the formation of gas bubbles in the blood stream. Finally, the physicist and acoustical engineer must cope with the cavitation problem when working with underwater transducers, cavitation noise, and the propagation of acoustical signals through media in which cavitation is occurring.

There are many forces which hold a liquid together and must be overcome if cavities are to form. The most obvious force is the force holding the molecules of the liquid together. These intermolecular cohesive forces are of considerable magnitude and they are additive to the force exerted by the external pressure. When these additive forces have been overcome, cavities will form in a liquid.

The presence of impurities in a liquid will affect the tensile stress necessary to cause cavitation. Precisely how these impurities in a liquid influence cavitation is obscure, or at least subject to controversy, but it is clear no theory that ignores them explains adequately the observed facts.

The object of this investigation was to study the effects of ultrasonically-induced cavitation in distilled water at liquid heights in the two to fifteen centimeter range on known concentrations of carbon dioxide, bicarbonate ions, and oxygen. The ultrasonic power setting required to produce violent cavitation was studied as a function of distilled water height"--Introduction, pages 1-2.
