Conservation of Mass in Finite Cotrol Volume

The principle of conservation of mass is a fundamental law in fluid mechanics and is applied using the continuity equation. We apply the concept to a finite control volume to derive the continuity equation.

A system is defined as a collection of unchanging contents, and the conservation of mass states that a system's mass is constant.

The continuity equation is derived from the principle that the mass within a system remains constant.

To analyze fluid movement, we observe the mass within a fixed control volume, accounting for the mass inside and crossing the control surface.

The total change in mass includes the rate at which mass accumulates inside the control ...
