2.2.2 Control Volume, c.v.

The control volume was introduced by L. Euler In the control volume, c.v we are looking at spesific volume which mass can enter and leave. The simplest c.v. is when the boundry are fixed and it is refered to as the Non-deformable c.v.. The conservation of mass to such system can be very good approximated by

(2.6)

This equation states the change in the volume come from the difference of masses being added through the boundary.

put two examples of simple for mass conservation.

For deformable c.v.
