The drag on an airplane wing in flight is known to be a function of the following quantitiesρ - density of airμ - viscosity of airU?? - free-stream velocityS - characteristic dimension of the wingτs - shear stress on the surface of the wingShow that the dimensionless drag

can be expressed as a function of the Reynolds number

GIVENAn airplane wing in flightDrag on wing (D) = f (ρ, μ, U??, S,τs)
