continuity equation
which is a consequence of conservation of mass. Here ρ denotes density and u is the fluid's velocity. Consequently, if the fluid is incompressible and ρ is constant, then divu = 0. The term is more generally used for similar equations that arise in applied mathematics as a consequence of a quantity being conserved.
