Coefficient of drag sphere
WebDrag coefficient C d for a sphere as a function of Reynolds number Re, as obtained from laboratory experiments. The dark line is for a sphere with a smooth surface, while the lighter line is for the case of a rough surface. ... The drag coefficient depends on the shape of the object and on the Reynolds number WebJul 28, 2024 · The drag coefficient is a number which aerodynamicists use to model all of the complex dependencies of drag on shape , inclination, and some flow conditions. The drag coefficient Cd is equal to the drag D divided by the quantity: density r times reference area A times one half of the velocity V squared. Cd = D / (.5 * r * V^2 * A)
