WebOne of the fundamental principles used in the analysis of uniform flow is known as the Continuity of Flow. This principle is derived from the fact that mass is always conserved in fluid systems regardless of the pipeline complexity or direction of flow. WebCFD literature the term Navier-Stokes is usually used to include both momentum and continuity equations, and even energy equation sometimes). It is possible to write it in many different forms. One possibility is ⃗ ̿
