Wind Power Calculator: Energy vs Turbine Size vs Speed

The table provides data only for 10 m and 50 m heights To estimate the air speed and output for the actual height of your tower you can use an empirical 1/7 power law If you know the air speed V1 at a certain height h1, then the air speed V2 at a different height h2 can be estimated as: V2=V1×(h2/h1) 1/7
