WebAug 20, 2015 · The drag coefficient is no longer independent of the Reynolds number, increasing in value. For the case of a sphere, the drag coefficient becomes C D = 24 / Re, meaning values of C D = 24 for Re … WebApr 11, 2014 · experimentally, and how the data can be used to calculate a drag coefficient. Frontal area of the vehicle may be determined with internet resources, and …
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.
