Solved example: how big for continuity

Yes we can even analyze space dust. The continuity assumption means that we have a large enough system for our material's properties to be well defined. This creates a relationship between desired precision, and volume. More precision means higher volume. Of course this also depends on the density of material in the system. We explore the relationship here between precision, density and volume. Continuity Assumption Lecture:    • Fluid Mechanics Lecture 01: Intro and the ...
