Source of Downforce Formula for the Calculation of Wing Downforce?

Hey guys,

 

The wikipedia page for downforce displays the following formula as a means to calculate the downforce of a wing

 

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

 

where D= downforce in metres

WS = wingspan in metres

H=height in metres

alpha= angle of attack

F= lift coefficient

rho= air density in kg/m^3

V= Velocity in m/s

 

does anyone know the source of this formula? or the derivation of it? i need to reference/cite it for a university project.

 

Thanks.
