Enter the air density (kg/m^3) and the wind speed (m/s) into the Wind Power Density Calculator. The calculator will evaluate and display the Wind Power Density.

## Wind Power Density Formula

The following formula is used to calculate the Wind Power Density.

WPD = 1/2 * AD * WS^3

• Where WPD is the Wind Power Density (Watts/m^2)
• AD is the air density (kg/m^3)
• WS is the wind speed (m/s)

## How to Calculate Wind Power Density?

The following example problems outline how to calculate Wind Power Density.

Example Problem #1:

1. First, determine the air density (kg/m^3).
1. The air density (kg/m^3) is given as: 1.
2. Next, determine the wind speed (m/s).
1. The wind speed (m/s) is provided as: 5.
3. Finally, calculate the Wind Power Density using the equation above:

WPD = 1/2 * AD * WS^3

The values given above are inserted into the equation below:

WPD = 1/2 * 1 *5^3 = 62.5 (Watts/m^2)

Example Problem #2:

For this problem, the variables needed are provided below:

air density (kg/m^3) = 86

wind speed (m/s) = 74

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

WPD = 1/2 * AD * WS^3 = ?
