Venturi effect

Venturi Effect

The Venturi effect, also known as the Venturi tube, is a phenomenon in fluid dynamics that occurs when a fluid flows through a constricted section of a pipe. It was named after the Italian physicist Giovanni Battista Venturi, who first described the effect in the 18th century.

Principle

The Venturi effect is based on the principle of conservation of energy. According to this principle, the total energy of a fluid flowing through a pipe remains constant along the flow path. When the fluid passes through a constriction, the velocity of the fluid increases, while the pressure decreases. This relationship between velocity and pressure is described by Bernoulli's principle.

Application

The Venturi effect has various practical applications in different fields. One of the most common applications is in carburetors of internal combustion engines. In a carburetor, a Venturi tube is used to create a pressure difference that allows the fuel to be drawn into the engine's intake manifold.

Another application of the Venturi effect is in medical devices such as nebulizers and inhalers. These devices use the constriction of a Venturi tube to create a low-pressure area, which helps in the delivery of medication to the patient's respiratory system.
