Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In vector calculus, the divergence is an operator that measures the magnitude of a vector field's source or sink at a given point; the divergence of a vector field is a (signed) scalar. For example, consider air as it is heated or cooled. The relevant vector field for this example is the velocity of the moving air at a point. If air is heated in a region it will expand in all directions such that the velocity field points outward from that region. Therefore the divergence of the velocity field in that region would have a positive value, as the region is a source. If the air cools and contracts, the divergence is negative and the region is called a sink. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.The inward flux i.e. flux from source to sink is positive and the outward flux that is flux from sink to source is negative.The divergence of fluids velocity measures the rate at which fluid is being piped into or out of the region at any point so it is analogous to flux.
