Question

volumetric strain rate as the rate of increase of volume of a fluid element per unit volume. In Cartesian coordinates we write the volumetric strain rate as     1/ V  DV/Dt = ∂u/∂x + ∂?/∂y + ∂w/∂z
Write the primary dimensions of each additive term, and verify that the equation is dimensionally homogeneous. Show all your work.

Time = t2
Time = t1
Volume = V2
Volume = V,
