where ° is the tip speed ratio, a r is the solidity and ß = rj R. Over the outboard half of the blade, which produces the bulk of the power, the local speed ratio, will normally be large enough to enable the denominator to be approximated as giving:

where N is the number of blades. After rearrangement, this gives
