Question

Identify the true statements and expressions of a source flow. Check All That Apply $$\nabla \cdot \vec{V} = \infty$$ at the origin and $$\nabla \cdot \vec{V} = 0$$ everywhere else. The flow is a physically incompressible flow except at the origin. The flow is irrotational everywhere. The flow is irrotational everywhere except at the origin. The flow is a physically incompressible flow everywhere. $$\nabla \cdot \vec{V} = 0$$

Step 1

For a 3D point source of strength Q the velocity (for r>0) is V(r) = (Q/(4π r^2)) e_r. (For a 2D line source of strength m per unit length the velocity is V(r) = (m/(2π r)) e_r.) The important feature: V is purely radial and singular at r = 0. Show more…
