Fig. (1) shows the net drag force acting on a cylinder. The drag force is often non-dimensionalized as a function of Reynolds number. This is then referred to as the drag coefficient (eq. 1). fiu law school redditWebThe drag coefficient (non-dimensional drag) is equal to the drag force divided by the product of velocity pressure and frontal area. The velocity may be that of the object through the air (or any other gas) or the air velocity past a stationary object.
