What is a venturi meter?

What is a venturi meter?

How it Works? Venturi meter is a device used to measure the flow rate or discharge of fluid through a pipe. Venturimeter is an application of Bernoulli’s equation.

What is the venturi effect?

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 its discoverer, Giovanni Battista Venturi .

How do you measure pressure difference in a venturi?

The pressure difference is measured by using a differential U-tube manometer. This pressure difference helps in the determination of the rate of flow of fluid or discharge through the pipeline. As the inlet area of the venturi is large than at the throat, the velocity at the throat increases resulting in a decrease of pressure.

What is the coefficient of discharge for a venturi meter?

The coefficient of discharge (Cd) for the venturi meter is high. This is widely used for a high flow rate (Discharge). The installation cost of a venturi meter is high. There are little difficulties while maintenance.

A venturi meter is a device used to measure the fluid flow through pipes. This flow measurement device is based on the principle of Bernoulli’s equation.

Who invented venturimeter?

The principle of the Venturimeter was demonstrated by Giovanni Batista Venturi (Hence the name Venturimeter), But it was first used in practical metering applications by Clemens Herschel. In this article, we will explore the parts, working principles, equations, and applications of the Venturimeter.

What are the requirements of a venturimeter?

Require long laying length. That is, the venturimeter has ti be proceeded by a straight pipe which is free from fittings and misalignments to avoid turbulence inflow, for satisfactory operation. Therefore, straightening vanes are a must.
