Abstract

Starting from this chapter and to the end of the first part we are building a closed system of equations of a fluid model. Firstly, we discuss differential conservation laws, and related balance equations. All previously obtained expressions are applied then to the mass of a body, and this gives the first equation of the fluid model, the continuity equation.

Keywords:

Balance equation, Compressibility, Continuity equation, Differential conservation law, Flow through a surface, Flux, Levi-Civita symbol, Mass flux density, Rate of volume expansion.
