Compressible and incompressible flow

Compressible flow and Incompressible flow

According to the theory of aerodynamics, the flow is said to be compressible if the density changes with the stream line. The Mach number in the flow exceeds 0.3. Incompressible flow is a flow in which density is constant in both time and space. A flow is classified as being compressible or incompressible depending on the level of variety of density amid stream. Incompressibility is an estimation and a stream are said to be incompressible in the event that the thickness remains about constant all through. The densities of fluids are basically constant at a specific temperature and thus the stream of fluids is ordinarily incompressible. So, fluids are frequently referred to as incompressible fluids.
