## Power Density Formula

The following formula is used to calculate the Power Density.

Dp = P / (L*W)

- Where Dp is the Power Density (W/ft^2)
- P is the total power (watts)
- L is the total length (ft)
- W is the total width (ft)

To calculate the power density, divide the power by the product of the length and the width.

## How to Calculate Power Density?

The following example problems outline how to calculate Power Density.

**Example Problem #1**

- First, determine the total power (watts).
- The total power (watts) is given as 300.

- Next, determine the total length (ft).
- The total length (ft) is calculated as: 3.

- Next, determine the total width (ft).
- The total width (ft) is found to be: 10.

- Finally, calculate the Power Density using the formula above:

Dp = P / (L*W)

Inserting the values from above yields:

Dp = 300 / (3*10) = 10 (W/ft^2)

**Example Problem #2**

The variables needed for this problem are provided below:

total power (watts) = 500

total length (ft) = 1206

total width (ft) = 5

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. Dp = P / (L*W) =** **(W/ft^2)
