drag coefficient

[′drag ‚kō·i′fish·ənt]
(fluid mechanics)
A characteristic of a body in a flowing inviscous fluid, equal to the ratio of twice the force on the body in the direction of flow to the product of the density of the fluid, the square of the flow velocity, and the effective cross-sectional area of the body.

drag coefficient

drag coefficient
A typical drag coefficient curve of an airfoil.
i. Nondimensional coefficient equal to total drag divided by ¼ ρ V2S, where ρ is density, V is indicated air speed, and S is surface area of the body.
ii. A coefficient representing the drag on a given airfoil or other body or a coefficient representing a particular element of drag.
