Calculation/ Mathematical Tools:

Sweep Area of Blades  pi x Radius² = Area Swept by the Blades.

Metric Turbine Blade Tip Speed Calculator

Example of how to calculate blade tip speeds:

A 2.5 MW wind turbine has a diameter of 100 m. Therefore, the blade tip traces a circumference of 100 m times pi = 314.159 m / revolution. Using 16 revolutions per minute example, the calculations are:

  • 16 revolutions per minute x 314.159 m = 5026.55 m per minute
  • 5026 m per minute x 60 minutes per hour = 301,593 m per hour
  • 301,593 m per hour / 1,000 m per km = 302 km/h!
