## Nozzle Velocity Formula

The following equation is used to calculate the Nozzle Velocity.

V = mdot / (p*A)

- Where V is the nozzle exit velocity (m/s)
- mdot is the mass flow rate out of the nozzle (kg/s)
- p is the density of the fluid (kg/m^3)
- A is the cross-sectional area of the nozzle (m^2)

To calculate nozzle velocity, divide the mass flow rate by the product of the density and area.

## What is a Nozzle Velocity?

Definition:

Nozzle velocity describes the linear flow rate of a fluid moving out of a nozzle.

## How to Calculate Nozzle Velocity?

Example Problem:

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

First, determine the mass flow rate out of the nozzle. In this example, the mass flow rate out of the nozzle is found to be 50 kg/s.

Next, determine the density of the fluid. For this problem, the density of the fluid is found to be 500 kg/m^3.

Next, determine the cross-sectional area of the nozzle. In this case, the cross-sectional area of the nozzle is measured to be .25 m^2.

Finally, calculate the Nozzle Velocity using the formula above:

V = mdot / (p*A)

V = 50 / (500*.25)

V = .4 m/s
