Fluid Dynamics Homework Question 2?
2. If the velocity field is �'⃗ = (�, �, �), with u, v, w being the velocity component in x, y, and z
directions, respectively, show that the term ∇ ∙ �'⃗ indicates the volumetric dilatation rate, that is
the fraction of volume increase per unit time. (hint: use the divergence theorem)
