I know that Stoke's Law of F=6(pi)RnVc, where R is the radius of the sphere, n is the viscosity, and Vc is the velocity through a continuous fluid, can give the viscous drag on a sphere, but was informed that this only applies to very small spheres, so it is no use in my application for the drag on a soccer ball.

I also know of the formula that Force(drag) = 0.5 C.P.A.v^2 where C = coefficient of drag, P = fluid density, A = area of the object, v = velocity of the object, but I didn't know which aspect of the drag force (pressure, viscous or total drag) this formula calculates.

If anyone could help me out here that would be greatly appreciated.

Thanks, Adam
