While all flows are compressible, flows are usually treated as being incompressible when the Mach number (the ratio of the speed of the flow to the speed of sound) is smaller than 0.3 (since the density change due to velocity is about 5% in that case).

An equivalent statement that implies incompressibility is that the divergence of … See more The fundamental requirement for incompressible flow is that the density, $${\displaystyle \rho }$$, is constant within a small element volume, dV, which moves at the flow velocity u. Mathematically, this … See more An incompressible flow is described by a solenoidal flow velocity field. But a solenoidal field, besides having a zero divergence, also has the additional connotation of … See more In fluid dynamics, a flow is considered incompressible if the divergence of the flow velocity is zero. However, related formulations can sometimes be used, depending on the flow system being modelled. Some versions are described below: See more In some fields, a measure of the incompressibility of a flow is the change in density as a result of the pressure variations.
