What Is Venturimeter?

A Venturimeter is a specialized device used to measure the flow rate of fluids, particularly liquids, in a pipeline. Named after its inventor, Giovanni Battista Venturi, this apparatus employs the principle of fluid dynamics to provide accurate readings of fluid flow. It consists of a tapered tube section that narrows and then widens, creating a pressure difference used for flow measurement.

What Is Venturimeter Used For?

The primary purpose of a Venturimeter is to measure fluid flow rates in pipelines. Its applications span various industries, including water supply systems, chemical plants, and manufacturing processes. By accurately gauging the flow of liquids, Venturimeters play a crucial role in maintaining operational efficiency and ensuring optimal performance of fluid systems.

What Is Venturimeter In Fluid Mechanics?

In fluid mechanics, a Venturimeter serves as a vital tool for studying fluid flow dynamics. The device leverages Bernoulli’s principle, which states that as the speed of a fluid increases, its pressure decreases. The Venturimeter capitalizes on this principle to determine the flow velocity of liquids, making it an indispensable asset in the field of fluid mechanics.

What Is Venturimeter Formula?

The Venturimeter formula is essential for calculating the flow rate of fluids accurately. The formula involves parameters such as the cross-sectional areas of the pipe, throat, and the pressure difference between these points.


  • Q is the flow rate,
  • A1 and A2are the cross-sectional areas of the pipe and throat, respectively,
  • Cd is the discharge coefficient,
  • g is the acceleration due to gravity, and
  • ℎ is the pressure difference.

  • Throat Diameter. …
  • Diverging Cone. …
  • Horizontal Venturimeter.
  • Vertical Venturimeter.
  • Inclined Venturimeter.

Which Principle Is Used In Venturimeter?

Venturimeter works on the principle of Bernoulli’s equation.

What Is A Venturi?

A Venturi is a system for speeding the flow of the fluid, by constricting it in a cone shape tube. In the restriction the fluid must increase its velocity reducing its pressure and producing a partial vacuum. As the fluid leave the constriction, its pressure increase back to the ambient or pipe level.
