What is the physical meaning of divergence

For example, the figure on the left has positive divergence at p, since the vectors of the vector field are all spreading as they move away from p.Assume that s be a closed surface and any line drawn parallel to coordinate axes cut s in almost two points.F → = f 1 i → + f 2 j → + f 3 k →.Divergence at a point measures the flux flowing out from an infinitesimal volume around that point.For example, this diagram from the wiki page shows how energy flows from a battery to a resistor in a simple circuit.The definition of the divergence therefore follows naturally by noting that, in the absence of the creation or destruction of matter, the density within a region of space can change only by having it flow into or out of.

What is the physical meaning of divergence of velocity?If you measure flux in bananas (and c'mon, who doesn't?), a positive divergence means your location is a source of bananas.When the initial flow rate is less than the final flow rate, divergence is positive (divergence > 0).Physical interpretation of divergence in physical terms, the divergence of a vector field is the extent to which the vector field flux behaves like a source at a given point.
