WebJan 9, 2024 · 1 Answer Sorted by: 2 Use the divergence theorem. Let M be the solid ellipsoid, so ∂ M is its surface. Then ∬ ∂ M u ⋅ d A = ∭ M ∇ ⋅ u d V The divergence ∇ ⋅ u = 3 everywhere, so it's 3 times the volume of the ellipsoid. The volume of an ellipsoid is given by 4 3 π a b c, so the flux is 4 π a b c.

WebThe flow rate of the fluid across S is ∬ S v · d S. ∬ S v · d S. Before calculating this flux integral, let’s discuss what the value of the integral should be. Based on Figure 6.90, we see that if we place this cube in the fluid (as long as the cube doesn’t encompass the origin), then the rate of fluid entering the cube is the same as the rate of fluid exiting the cube.
