Differential element in spherical coordinates

WebTo do the integration, we use spherical coordinates ρ,φ,θ. On the surface of the sphere, ρ = a, so the coordinates are just the two angles φ and θ. The area element dS is most easily found using the volume element: dV = ρ2sinφdρdφdθ = dS ·dρ = area · thickness so that dividing by the thickness dρ and setting ρ = a, we get WebMar 5, 2024 · The net mass change, as depicted in Figure 8.2, in the control volume is. d ˙m = ∂ρ ∂t dv ⏞ drdzrdθ. The net mass flow out or in the ˆr direction has an additional term which is the area change compared to the Cartesian coordinates. This change creates a different differential equation with additional complications.
