WebDrag coefficient(Cd) is a commonly published rating of a car's aerodynamic smoothness, related to the shape of the car. Multiplying Cdby the car's frontal area gives an index of total drag. The result is called drag area, and is listed below for several cars. The width and height of curvy cars lead to gross overestimation of frontal area. med for pancreatitisWebThe drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag.
