  Section 3: Mass Conservation of Flowing Media
  3.1 Law of mass conservation for a continuum, expressed in control volume form. Examples.
  3.2 Mass conservation law in differential form. The physical significance of the divergence of the velocity: = the rate of increase of the material’s volume, per unit volume.
  3.3 Some special forms of the mass conservation equation for quasi-one-dimensional flow, accounting for the effects of unsteadiness, compressibility, and cross-sectional area variations. Examples.
