Question

when the divergence is....
the flux entering any volume element is the by that leaving through that volume element​

Answer 1

Answer:

the vector field is increasing in magnitude as you move along the flow of a vector field, then the divergence is positive. If the vector field is decreasing in magnitude as you move along the flow of a vector field, then the divergence is negative.

Answer 2

A vector field's divergence is a scalar function. The "outflowing-ness" of a vector field is measured by divergence. The outflow of the fluid less the inflow at a place is the divergence of v at a point if v is the velocity field of a fluid.
