A venturi meter is a device which is used for measuring the rate of flow of fluid through a pipe. The basic principle on which a venturi meter works in that by reducing the cross-sectional area of the flow passage, a pressure difference is created and the measurement of the pressure difference enables the determination of the discharge through the pipe.

Venturimeter and Its Application
Venturimeter:
A venturimeter is a device that is used to measure the rate of flow of a fluid in a pipe. It is a type of flow meter that is based on the Bernoulli's principle. It consists of a converging section, a throat section, and a diverging section.
Working Principle:
The venturimeter works on the principle of Bernoulli's equation. Bernoulli's equation states that as the speed of the fluid increases, the pressure decreases. In a venturimeter, the fluid flows through a narrowing section of the pipe, which increases the velocity of the fluid and decreases the pressure. The pressure difference is measured using a differential pressure gauge, which is connected to two pressure taps located at the upstream and downstream of the venturimeter.
Application:
Venturimeters are commonly used in the following applications:
- Measurement of flow rate of liquids in pipes
- Measurement of flow rate of gases in pipes
- Measurement of flow rate of steam in pipes
Measurement:
The venturimeter is used to measure the rate of flow of a fluid in a pipe. The rate of flow is measured by the differential pressure gauge, which is connected to two pressure taps located at the upstream and downstream of the venturimeter. The pressure difference is proportional to the flow rate of the fluid.
Conclusion:
In conclusion, a venturimeter is a flow meter that is used to measure the rate of flow of a fluid in a pipe. It works on the principle of Bernoulli's equation and is commonly used in the measurement of flow rate of liquids, gases, and steam in pipes. The venturimeter is a reliable and accurate method of measuring flow rates and is widely used in various industries.
