drag coefficient
where F is the drag force, ρ (rho) is the air density, V is the air velocity, and A is the cross sectional area. All of these, except Cd, are directly measurable in a wind tunnel so Cd can be thought of the "fudge factor" that accounts for all of the aerodynamic peculiarities of a shape.
