Webwhere r is the sphere radius. The Stokes’ law thus describes the fact that the magnitude of the drag for a small Reynolds number is proportional to the magnitude of the velocity of the body. In general, Newton’s formula is used to describe the drag for different body shapes and different velocities, which reads F = 1 2 CρSv2, (1.4) Web1. Stoke's theorem states that for a oriented, smooth surface Σ bounded simple, closed curve C with positive orientation that. ∬ Σ ∇ × F ⋅ d Σ = ∫ C F ⋅ d r. for a vector field F, where ∇ × F denotes the curl of F. Now the surface in question is the positive hemisphere of the unit sphere that is centered at the origin.
