## Neutron Velocity Formula

The following equation is used to calculate the Neutron Velocity.

Vn = 1.383 * 10 ^6 * SQRT( E) /100

- Where Vn is the neutron velocity (m/s)
- E is the neutron energy (eV)

## What is a Neutron Velocity?

Definition:

A neutron velocity is the measure of speed of a neutron based on it’s mass and kinetic energy.

## How to Calculate Neutron Velocity?

Example Problem:

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

First, determine the neutron energy. In this example, the neutron energy is found to be 500 eV.

Finally, calculate the Neutron Velocity using the formula above:

Vn = 1.383 * 10 ^6 * SQRT( 500) /100

Vn = 1.383 * 10 ^6 * SQRT( 500) /100

Vn = 309,248.201 m/s
