The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe. The Venturi effect is named after Giovanni Battista Venturi (1746–1822), an Italian physicist.


The carburettor used in many reciprocating engines contains a venturi to create a region of low pressure to draw fuel into the carburettor and mix it thoroughly with the incoming air. The low pressure in the throat of a venturi can be explained by Bernoulli's principle; in the narrow throat, the air is moving at its fastest speed and therefore ...


The Venturi effect, published in 1797 by Giovanni Venturi, applies Bernoulli's principle to a fluid that flows through a tube with a constriction in it, such as in figure 2. The Venturi tube provides a handy method for mixing fluids or gases, and is popular in carburetors and atomizers, which use the low pressure region generated at the ...


What Is an Explanation of the Venturi Effect? What Is an Explanation of the Venturi Effect? According to About.com Scuba Diving, the Venturi effect states that when air is forced through a narrow tube, the air particles leave the tube traveling at a greater speed than when they entered the tube. ... venturi principle explained venturi effect ...


Carburettor Venturi and vaporization: While the carburettor atomizes most of the fuel in the mixing chamber, it vaporizes only a small part of the fuel. The amount of fuel vaporized depends upon the nature of the fuel, the temperature of the air, fuel and engine parts, the amount of suction created above the fuel jet and the degree to which the fuel is broken up or atomized.


The Venturi Principle A venturi creates a constriction within a pipe (classically an hourglass shape) that varies the flow characteristics of a fluid (either liquid or gas) travelling through the tube. As the fluid velocity in the throat is increased there is a consequential drop in pressure. Italian scientist Giovanni B Venturi (1746-1822) was ...


The Venturi effect was named after Italian physicist, Giovanni Battista Venturi, who lived from 1746-1822. Venturi was ordained as a priest in 1769 and was a student of Lazzaro Spallanzani. He is not only given credit for the effect’s discovery, but is also credited with the inventions of the Venturi pump and tube.


According to Bernoulli's principle, the flow speed of a fluid is inversely proportional to its static pressure. This means that, when the velocity of the fluid increases, its pressure will decrease. The Venturi effect is a version of the Bernoulli's principle, but more specifically suited to the flow of fluids through a pipe.
