In fluid mechanics, dewetting is one of the processes that can occur at a solid–liquid, solid–solid, or liquid–liquid interface. Generally, dewetting describes the process of retraction of a fluid from a non-wettable surface it was forced to cover. The opposite process—spreading of a liquid on a substrate—is called wetting. The factor determining the spontaneous spreading and dewetting for a drop of liquid placed on a solid substrate with ambient gas, is the so-called spreading coefficient : thumb|right|Surface tension diagram of a liquid droplet on a solid substrate.

In fluid mechanics, inertance is a measure of the pressure difference in a fluid required to cause a unit change in the rate of change of volumetric flow-rate with time. The base SI units of inertance are or and the usual symbol is .

Hydrodynamica, sive de Viribus et Motibus Fluidorum Commentarii (Latin for Hydrodynamics, or commentaries on the forces and motions of fluids) is a book published by Daniel Bernoulli in 1738. The title of this book eventually christened the field of fluid mechanics as hydrodynamics.
