The formula to calculate the Turbulence Intensity (TI) is:
\[ TI = \left( \frac{\sigma}{V} \right) \times 100 \]
Where:
Let's say the standard deviation of the wind speed (σ) is 2 m/s, and the mean wind speed (V) is 10 m/s. Using the formula:
\[ TI = \left( \frac{2}{10} \right) \times 100 = 20 \% \]
So, the turbulence intensity is 20%.
