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 from one section of a pipe to a smaller section. The Venturi effect is named after its discoverer, the 18th-century Italian physicist Giovanni Battista ...
Fertigation is the injection of fertilizers, used for soil amendments, water amendments and other water-soluble products into an irrigation system. Chemigation, the injection of chemicals into an irrigation system, is related to fertigation.
Farmers accomplish fertilizing large sections of crops by combining water-soluble fertilizer and water in a tank, where it is then expelled by the injectors onto waiting crops. This process is known as fertigation. By injecting a specified amount of concentrated fertilizer into the device, the injector mixes this into what is called a stock ...
Fertigation can easily be included with minimal waste of fertilizers. Foliage remains dry, reducing the risk of disease. Usually operated at lower pressure than other types of pressurized irrigation, reducing energy costs. The disadvantages of drip irrigation are: Initial cost can be more than overhead systems.
A vacuum ejector, or simply ejector, or aspirator, 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.
Giovanni Battista Venturi (11 September 1746 – 10 September 1822) was an Italian physicist, savant, man of letters, diplomat and historian of science.He was the discoverer of the Venturi effect, which was described in 1797 in his Recherches Experimentales sur le Principe de la Communication Laterale du Mouvement dans les Fluides appliqué a l'Explication de Differens Phenomènes Hydrauliques ...
Clemens Herschel (March 23, 1842 – March 1, 1930) was an American hydraulic engineer.His career extended from about 1860 to 1930, and he is best known for inventing the Venturi meter, which was the first large-scale, accurate device for measuring water flow.
So if Air under pressure is forced through a venturi tube it will be able to suck a liquid in through a small hole producing aerated liquid. eg The Venturi effect is used when a coffee machine uses steam under pressure to draw up and froth milk. 202.138.204.101 01:44, 1 December 2006 (UTC) That is also how carburetors work.
