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 flux form of Green’s theorem relates a double integral over region $D$ to the flux across boundary $C$. The flux of a fluid across a curve can be difficult to calculate using the flux line integral. This form of Green’s theorem allows us to translate a difficult flux integral into a double integral that is often easier to calculate. 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.
