Terminal velocity of a settling sphere in 2D vs 3D

Web0. Terminal velocity can be found from the balance of forces : buoyancy force + drag force = weight. where the drag depends on the velocity U of the cylinder through the fluid (or the velocity of the fluid past the cylinder) in some unknown way. Buoyancy cannot be neglected unless the density of the disk is much greater than that of the fluid.
