How do you calculate Venturimeter?
Venturimeter Equations
- p= pressure inside the pipe.
- ρ =density of the fluid.
- g =gravitational constant.
- v = velocity.
- z=elevation or head.
- a = cross-sectional area of the pipe.
- d= diameter of the pipe.
What is Venturi meter in physics?
A Venturi-meter is a device which is used to measure the rate of flow of a liquid through a pipe. It is an application of Bernoulli’s principle. It consists of a tube with a broad diameter and a small constriction at the middle as shown in the figure above.
What is the basic principle of Venturi meter?
The principle behind the operation of the Venturi flowmeter is the Bernoulli effect. The Venturi measures a fluid’s flowrate by reducing the cross sectional flow area in the flow path and generating a pressure difference.
What does Venturi meter measure?
Venturimeter is a device used to measure the rate of flow of fluid flowing through a pipe.
Can Venturi meter be used vertically?
In principle, the homogeneous model can be used with horizontally and vertically oriented Venturis.
What is the difference between Orificemeter and Venturimeter?
Venturi meter and orifice meter are used for measuring the volumetric flow rate of the fluid that based on the continuity equation and Bernoulli’s equation. The difference between venturi meter and orifice meter are: The coefficient of discharge in the venturi meter is 0.98 while in orifice meter it is 0.6.
Where in the Venturi meter is the pressure the highest?
The static pressure in the first measuring tube (1) is higher than at the second (2), and the fluid speed at “1” is lower than at “2”, because the cross-sectional area at “1” is greater than at “2”.
What are the advantages and disadvantages of Venturi meter?
Venturi meter:
- Less chance of getting stuck with sediment.
- The discharge coefficient is high.
- Its behaviour can be predicted perfectly.
- It can be installed vertically, horizontally, inclined.
- They are more precise and can be used for a wide range of flows.
- About 90% of the pressure drop can be recovered.
What is the purpose of Venturi meter?
A venturi meter is a measuring or also considered as a meter device that is usually used to measure the flow of a fluid in the pipe. A Venturi meter may also be used to increase the velocity of any type fluid in a pipe at any particular point.
What is Venturi meter explain its working and theory?
Venturimeter works on the principle of Bernoulli’s equation i.e when velocity increases pressure decreases . Since the cross -section decreases from inlet pipe to throat, the velocity of the fluid increases and hence the pressure decreases.
Why is Venturi meter used?
Venturi meters are flow measurement instruments which use a converging section of pipe to give an increase in the flow velocity and a corresponding pressure drop from which the flowrate can be deduced. They have been in common use for many years, especially in the water supply industry.
