Conservation of Mass

This video is for representing the conservation of mass equation in integral form and deducing the expression in differential form.
The first part of derivation is Eulerian integral representation, which is deduced to Eulerian differential form and then to Lagrangian differential form.
The conservation law is explained in separate video the link of which is

This video will help listener to understand what is continuity equation and what is flow rate equation. How they are derived, from which form.
