Enter the flow velocity and the cross-sectional area into the calculator to determine the volumetric flow rate of a fluid.

## Volumetric Flow Rate Formula

The follow equation is used to calculate the volumetric flow rate of a fluid moving through a pipe.

V = A*v

- Where V is the volumetric flow rate
- A is the cross-sectional area (m^2)
- v is the flow velocity (m/s)

## Volumetric Flow Rate Definition

A volumetric flow rate is the total volume of fluid moving through a cross-sectional area per unit of time.

## Volumetric Flow Rate Example

How to calculate volumetric flow rate?

**First, determine the cross-sectional area.**Measure the area the fluid is moving through.

**Next, determine the flow velocity.**Calculate or measure the velocity of flow.

**Finally, calculate the volumetric flow rate.**Calculate the VFR using the equation above.

## FAQ

**What is volumetric flow rate?**

Volumetric flow rate is the rate at which a given volume of fluid flows through the opening of an area. In other words, how much volume is passing through a point per time or second.

**What is flow velocity?**

Flow velocity is the speed that any given particle of a fluid is moving at.
