Enter the volumetric flow rate and the area of the liquid flow into the calculator to determine the liquid flow rate.

## Liquid Velocity Formula

The following equation is used to calculate the Liquid Velocity.

LV = FR / A
• Where LV is the liquid velocity (ft/s)
• FR is the liquid flow rate (ft^3/s)
• A is the area of liquid flow (ft^2)

To calculate the liquid velocity, divide the liquid flow rate by the liquid flow area.

## What is a Liquid Velocity?

Definition:

Liquid velocity describes the linear speed of a liquid or fluid through a given area.

## How to Calculate Liquid Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Liquid Velocity.

First, determine the liquid flow rate. In this example, the liquid flow rate is found to be 20 ft^3/s.

Next, determine the area of liquid flow. In this case, the area of liquid flow is measured to be 5ft^2.

Finally, calculate the Liquid Velocity using the formula above:

LV = FR / A

LV = 20 / 5

LV = 4 ft/s
