VENTURI PUMP Meaning and
Definition
-
A venturi pump is a type of fluid transfer or suction device that operates based on the principle of Bernoulli's equation and the venturi effect. It consists of a specially designed tube or pipe with a narrow throat or constriction in the middle, resulting in a decrease in the internal pressure of the fluid passing through.
The working mechanism of a venturi pump involves a high-pressure fluid stream passing through the wider section of the tube, which accelerates as it reaches the narrow throat. According to Bernoulli's equation, as the fluid accelerates, its pressure decreases. This pressure drop creates a vacuum or suction effect at the throat of the venturi pump, which allows the pump to draw in a fluid or gas from a connected source.
Venturi pumps are commonly used in various applications where fluid or gas needs to be transferred, mixed, or withdrawn without the need for external power sources or moving parts. They are known for their simplicity, reliability, and low maintenance requirements. Additionally, venturi pumps can handle a wide range of fluid and gas types, including liquids, slurries, and gases of various viscosities.
Due to their effectiveness in creating a vacuum or suction effect, venturi pumps find applications in industries such as agriculture, chemical processing, wastewater treatment, and automotive. They are utilized for tasks such as pumping liquids, mixing chemicals, aspirating fluids, and creating smoke or fume extraction systems.
Etymology of VENTURI PUMP
The word "venturi" in "venturi pump" is derived from the name of the Italian physicist Giovanni Battista Venturi (1746-1822). Giovanni Venturi was known for his discoveries and experiments with fluid dynamics, including the principle now known as the Venturi effect. This principle states that as the speed of a fluid increases, its pressure decreases, creating a vacuum. The venturi pump utilizes this principle to create suction and move fluids.
