The shape of the curves F = f (V2) shows the proportionality between the aerodynamic drag force and the velocity squared. For each shape, a slope is determined and thanks to the relation below, the aerodynamic coefficient is estimated.
F = 1/2 x ρ x S x Cx v² where ρ is the air density, S is the cross-section of each piece in m², Cx is the aerodynamic coefficient which is specific to the shape (without unit) and v the speed of the air flow in m.s-1.
The aerodynamic quality of a profile is linked to its aerodynamic coefficient.
The more aerodynamic the profile, the lower the coefficient!
