Drag modeling. It was done in the 1840’s by Sir George Gabriel Stokes. He found what has become known as Stokes’ Law: the drag force F F on a sphere of radius a moving through a fluid of viscosity η η at speed v v is given by: F = 6πaηv (1.7.1) (1.7.1) F = 6 π a η v. This drag force is directly proportional to the radius.
