originally used l in place of a (l being some length). f d = ρ v c d a , {\displaystyle f_{d}\,=\,{ frac { }{ }}\, ho \,v^{ }\,c_{d}\,a,} see derivation the reference area a is often orthographic projection of the object (frontal area)—on a plane perpendicular to the direction of motion—e.g. for objects
with well-defined fixed separation points, like a circular disk with its plane normal to the flow direction, the drag coefficient is constant for re > . [ ] further the drag coefficient cd is, in general, a function of the orientation of the flow with respect to the object (apart from symmetrical objects...
