WebLecture 24: Divergence theorem There are three integral theorems in three dimensions. We have seen already the fundamental theorem of line integrals and Stokes theorem. Here is the divergence theorem, which completes the list of integral theorems in three dimensions: Divergence Theorem. Let E be a solid with boundary surface S oriented so … 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.
