Best Answer

Flow in a venturi meter refers to the rate at which a fluid passes through the device. The flow of fluid is measured by the pressure difference created between the converging and diverging sections of the venturi meter. This pressure difference is directly related to the flow rate of the fluid passing through the venturi meter.

How do you measure the flow?

Flow can be measured using instruments such as flow meters or by calculating flow rate using the formula Q = A * V, where Q is the flow rate, A is the cross-sectional area of the flow, and V is the velocity of the fluid. Measuring devices like mass flow meters, ultrasonic flow meters, and electromagnetic flow meters are commonly used for measuring flow in various industries.


Difference between uniform and non-uniform flow of fluid?

Uniform flow occurs when the fluid velocity and properties are constant throughout the flow field, while non-uniform flow has varying velocity and properties across the flow field. In uniform flow, streamlines are parallel and the flow is steady, whereas in non-uniform flow, streamlines may converge or diverge and the flow can be unsteady.


What is the definition of steady and unsteady flow of fluid?

Steady flow of fluid is when the flow parameters (velocity, pressure, density) at a point do not change with time. Unsteady flow is when these parameters vary with time at a particular point.


Steady flow and non steady examples?

Steady flow: Water flowing through a pipe at a constant rate with uniform velocity is an example of steady flow. Non-steady flow: Waves in the ocean where the water motion is constantly changing in both intensity and direction represent non-steady flow.


An irregular fluid flow is what?

An irregular fluid flow refers to a fluid motion that is not consistent or smooth, characterized by fluctuations and turbulence in the flow pattern. It can be caused by factors such as obstacles in the fluid's path, changes in the flow velocity, or variations in fluid properties. Irregular fluid flow can affect the efficiency and performance of systems where fluids are involved, such as pipelines or aircraft wings.

Will there be any flow variations if a venturimeter inlet outlet connections is reversed?

Yes, reversing the inlet and outlet connections of a venturi meter will result in flow measurement errors. The design of the venturi meter relies on the inlet and outlet connections being in a specific orientation to accurately measure fluid flow rates. Reversing the connections disrupts the flow dynamics and can lead to inaccurate readings.


What is venturi meter?

A Venturi meter is a device used to measure the flow rate of fluids in a pipeline. It consists of a converging section followed by a throat and then a diverging section. The pressure difference between the converging and throat sections is used to determine the flow rate of the fluid passing through the device.


Why is the coefficient of discharge of a venturimeter calculated?

The coefficient of discharge of a venturi meter is calculated to account for any discrepancies between the theoretical flow rate and the actual flow rate. It helps in correcting for losses due to friction and other factors in the fluid flow, and ensures accurate measurement of the flow rate through the venturi meter.


Why the diverging angle is smaller than converging angle for a venturimeter?

If the angle is greater than that, the pressure increases too quickly and the adverse pressure gradient will cause flow separation along the walls. By keeping the angle small, the flow remains attached and behaves nicely.


Applications of venturimeter?

1. It is used for flow measerment with minimum head loss. 2. It is used in industries for flow measerment of chemicals. 3. it is also used in the airoplane for measurment of speed of plane.
