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:
- First, determine the air density (kg/m^3).
- The air density (kg/m^3) is given as: 1.
- Next, determine the wind speed (m/s).
- The wind speed (m/s) is provided as: 5.
- 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 = ?
