Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

The following formula is provided on the wikipedia page for downforce,

D=0.5(WS)*H*alpha*F*rho*V^2

Where:

D is downforce in newtons

WS is wingspan in metres

H is height in metres

\alpha is angle of attack

F is lift coefficient

rho, ρ, is air density in kg/m³

V is velocity in m/s

Does anybody know the source of this Formula or how its is derived? I need to reference/cite it for a university project but can't find it anywhere. We are not able to reference wikipedia articles.

Thanks
