WebMar 3, 2016 · Interpret a vector field as representing a fluid flow. The divergence is an operator, which takes in the vector-valued function defining this vector field, and outputs a scalar-valued function measuring the change in density of the fluid at each point. The formula for divergence is. div v ⃗ = ∇ ⋅ v ⃗ = ∂ v 1 ∂ x + ∂ v 2 ∂ y + ⋯. WebNov 29, 2024 · The Divergence Theorem. Let S be a piecewise, smooth closed surface that encloses solid E in space.

WebDec 20, 2024 · Example 16.9.1. Let F = 2x, 3y, z2 , and consider the three-dimensional volume inside the cube with faces parallel to the principal planes and opposite corners at (0, 0, 0) and (1, 1, 1). We compute the two integrals of the divergence theorem. The triple integral is the easier of the two: ∫1 0∫1 0∫1 02 + 3 + 2zdxdydz = 6. WebThe theorem is sometimes called Gauss' theorem. Physically, the divergence theorem is interpreted just like the normal form for Green's theorem. Think of F as a three-dimensional flow field. Look first at the left side of (2). The surface integral represents the mass transport rate across the closed surface S, with flow out
