Wind Power Density Calculator

Formula

The formula to calculate the wind power density (WPD) is:

\[ WPD = \frac{1}{2} \times AD \times WS^3 \]

Where:

\( WPD \) is the Wind Power Density (W/m²).
\( AD \) is the air density (kg/m³).
\( WS \) is the wind speed (m/s).

Example

Let's say the air density (\( AD \)) is 1.225 kg/m³, and the wind speed (\( WS \)) is 10 m/s. Using the formula:

\[ WPD = \frac{1}{2} \times 1.225 \times 10^3 \]

We get:

\[ WPD = 0.5 \times 1.225 \times 1000 = 612.5 \]

So, the wind power density (\( WPD \)) is 612.5 W/m².

What is Wind Power Density?

Wind Power Density (WPD) is a measure of the amount of power available in the wind per unit area. It is calculated based on the air density and the wind speed. This metric is important for evaluating the potential of wind energy at a specific location.
