Stokes's law
An approximate relation, valid at low Reynolds numbers, for the drag force on a sphere moving relative to a fluid.
According to this law the drag on a sphere of radius a with speed v in a fluid with dynamic viscosity μ is Stokes's law is a good approximation for the drag on cloud droplets falling in air, but not on raindrops.
