Question

a material element is located at a(a, b, c) at time t0 with density 0 and subsequently at b(x, y, z) at time t with density . write the mass conservation relation for such an element.

Answer 1

element V = ∆x∆y∆z (Figure 3.1) and subsequently shrink this volume to a point by taking the limit ∆x → 0, ∆y → 0, ∆z → 0. .... values and generating only modest changes in density.

Answer 2

Ans ➡️ element V = ∆x∆y∆z (Figure 3.1) and subsequently shrink this volume to a point by taking the limit ∆x → 0, ∆y → 0, ∆z → 0. .... values and generating only

modest changes in density.

Hope this helps you ☺️☺️☺️☺️
