What is Venturimeter ? What is Venturimeter used for ? Which properties of liquids and gases are measured by Venturimeter ?

The Venturi tube is a mechanism for measuring the relationship between the velocities and pressures of moving fluids. The venturimeter is the flow meter using this device.
Italian physicist Giovanni Battista Venturi (1746-1822) invented the first flowmeter named Venturimeter in 1797 as a result of her work on fluids.
The venturimeter, which is used to measure the flow of fluids, has been developed by using the Venturi tube assembly.

The venturimeter is designed by placing a closed manometer at the inlet and outlet ends of a pipe with one side wide and the other narrow.

What is Venturimeter ?

Venturimeter is a device used to measure the flow rate of liquids. It has two ends, first one is the converging section. The fluid entered in this section causes increase in a velocity due to decreasing crossection causing increase in pressure drop (reduction in pressure).

What is Venturimeter used for ?

Venturimeter is a flow measurement instrument which uses a converging section of pipe to give an increase in the flow velocity and a corresponding pressure drop from which the flow rate can be deduced. They have been in common use for many years, especially in the water supply industry.

What is the use of Venturimeter ?

A Venturimeter is also called a Venturi Flowmeter. It is used to calculate the velocity of fluids in running through a pipeline. The fluid may be a liquid or a gas.

What is the working principle of a Venturimeter ?

A Venturimeter works on Bernoulli’s principle which states that the difference in pressure created across the obstruction gives the measure of the fluid flow rate. The flow rate is proportional to the square root of the differential pressure.

On what principal does a Venturimeter work ?

A Venturimeter works based on the equation of Bernoulli. The principle is named after Daniel Bernoulli who published it in his book Hydrodynamica in 1738.

What is Venturimeter used for ?

Venturimeter is an instrument used to measure the flow rate of fluids in general, which is open at both ends and narrows at both ends towards the middle of the section. It was first used by Italian physicist Giovanni Battista Venturi in 1797. Therefore, the device is called venturimeter.

As the fluid moving in a venturi passes through the venturi constriction zone, its velocity increases, and due to this increase, reverse pressure occurs in this zone. This reverse pressure created creates a vacuum effect in the contraction zone without spending extra energy and causes liquid - gas transfer.
