WebApr 10, 2024 · In January 2009 the Finnish ammunition manufacturer Lapua published Doppler radar tests derived drag coefficient data for most of their rifle projectiles. [1] [2] The predictive capabilities of the custom mode are based on actual bullet flight data derived from Doppler radar test sessions. WebAn important result in fluid dynamics is that the drag coefficient is a function only of the Reynolds number of the fluid flow about the object. That is, CD = CD(Re). C D = C D ( R e). This functional relationship has no closed form. However, the relationship has been established numerically based on experimental data.

For drag, this variable is called the … 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.
