The angular velocity of a windmill is a function of windmill diameter D, wind velocity V, air

The angular velocity Ω of a windmill is a function of windmill diameter D, wind velocity V, air density ρ, windmill height H as compared to atmospheric boundary layer height L, and the number of blades N: Ω = fcn(D, V, ρ, H/L, N). Viscosity effects are negligible. Rewrite this function in terms of dimensionless Pi groups.
