For a small spherical object of radius r and low Reynolds numbers, this quantity is given by 6 pi times the product of r, velocity, and dynamic viscosity, an equation known as Stokes' Law.
The d'Alembert paradox was resolved by Ludwig Prandtl's introduction of the boundary layer, in which most of this quantity is generated. In the limit of large Reynolds number, this quantity is proportional to the product of the square of velocity, area, and fluid density. For a small spherical object of radius r and low Reynolds numbers, this quantity is given by 6 pi times the product of r, velocity, and dynamic viscosity, an equation known as Stokes' Law. For 10 points, identify this force which impedes the motion of an object through a viscous fluid.
