The Netherlands is a country famous for its windmills
as a power generator. As we know that the windmill is
a device capable of converting wind energy into mechanical energy. Power
windmill mechanics P depends on the air density ρ, the cross-sectional area of the windmill
wind A, and air speed v. Using dimensional analysis, determine the power
wheel mechanics if the airspeed doubles its original !
