Venturi effect

The Venturi effect is the reduction in fluid pressure that results when a moving fluid speeds up as it is funneled from one section of a pipe to another, smaller section. As the fluid flows into a sma

A vacuum ejector, or simply ejector, or aspirator, is a type of vacuum pump, which produces vacuum by means of the Venturi effect.

…wine aerators. The reduction in pressure inside the constriction can be used both for measuring the fluid flow and for moving other fluids (e.g. in a vacuum ejector). In inviscid fluid dynamics, an incompressible fluid's velocity must increase as it passes through a constriction in accord with the principle of mass…
