Enter the flow through the orifice and the orifice area into the calculator to determine the orifice velocity.

## Orifice Velocity Formula

The following equation is used to calculate the Orifice Velocity.

VO = OF / OA

- Where VO is the orifice velocity (m/s)
- OF is the orifice flow rate (m^3/s)
- OA is the orifice area (m^3)

## What is an Orifice Velocity?

Definition:

An orifice velocity is a measure of the velocity of fluid moving through an orifice.

## How to Calculate Orifice Velocity?

Example Problem:

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

First, determine the orifice area. In this example, the orifice area is found to be 2 m^2.

Next, determine the orifice flow rate. In this case, the orifice flow rate is measured to be 50 m^3/s.

Finally, calculate the Orifice Velocity using the formula above:

VO = OF / OA

VO = 50 / 2

VO = 25 m/s
