Enter the diameter of the wires and the total number of wires into the calculator to determine the wire bundle diameter.

## Bundle Diameter Formula

The following equation is used to calculate the Bundle Diameter.

BD = SQRT ( 4 * (N*(PI*D^2/4)) / PI )
• Where BD is the bundle diameter (in)
• N is the number of wires
• D is the diameter of the wires

## What is a Bundle Diameter?

Definition:

A bundle diameter is the total diameter of a collection of wires packed in a circular shape.

## How to Calculate Bundle Diameter?

Example Problem:

The following example outlines the steps and information needed to calculate Bundle Diameter.

First, determine the diameter of wires. In, this case, the wire diameters are 50mm.

Next, determine the number of wires. For this bundle, there will be 100 wires.

Finally, calculate the bundle diameter using the formula above:

BD = SQRT ( 4 * (N*(PI*D^2/4)) / PI )

BD = SQRT ( 4 * (100*(3.14159*50^2/4)) / 3.141519)

BD = 500 mm.
