Knowledge-based, broadly deployed natural language. https://mathworld.wolfram.com/Divergence.html. The physical significance of the divergence of a vector field is the rate at which "density" exits a given region of space. The definition of the divergence therefore follows naturally by noting that, in the the element, written symbolically as, where is the vector field of fluid velocity.
