Video of a Venturi meter used in a lab experiment Idealized flow in a Venturi tube. The Venturi effect is the reduction in fluid pressure that results when a moving fluid speeds up as it flows through a constricted section (or choke) of a pipe. The Venturi effect is named after its discoverer, the 18th-century Italian physicist Giovanni ...
Choked flow is a fluid dynamic condition associated with the Venturi effect. When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a convergent-divergent nozzle or a valve in a pipe ) into a lower pressure environment the fluid velocity increases.
A vacuum ejector, or simply ejector is a type of vacuum pump, which produces vacuum by means of the Venturi effect. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.
The flow speed of a fluid can be measured using a device such as a Venturi meter or an orifice plate, which can be placed into a pipeline to reduce the diameter of the flow. For a horizontal device, the continuity equation shows that for an incompressible fluid, the reduction in diameter will cause an increase in the fluid flow speed.
Upstream contamination – Contaminants moving opposite of flow; Venturi effect – Reduced pressure caused by a flow restriction in a tube or pipe; Vortex – Fluid flow revolving around an axis of rotation; Water hammer – Pressure surge when a fluid is forced to stop or change direction suddenly
The American Federation of Government Employees (AFGE), the country's largest labor union for federal employees, is fighting back against GOP criticisms that government employees are abusing the ...
In hydrology, a Venturi flume is a device used for measuring the rate of flow of a liquid in situations with large flow rates, such as a river. [1] It is based on the Venturi effect, for which it is named. [2] It was first developed by V.M. Cone in Fort Collins, Colorado. [3] The Venturi flume consists of a flume with a constricted section in ...
Like many others who found themselves working remotely, Linette Miller, 59, noticed that she had become sedentary. “It suddenly dawned on me how little activity I get every day,” Miller, from ...
