Wind-speed power ratio calculator

The cubic ratio applies only with the other conditions unchanged and outside control limits.

Units

P_{2} / P_{1} = {V_{2} / V_{1}}^{3}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

P_{2} / P_{1} = {1.3}^{3} = 2.197

Symbol	Meaning	Unit
$P_{2} / P_{1}$	power ratio at equal area, density and capture	ratio
$V_{2} / V_{1}$	wind-speed ratio	ratio

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
