Which of the following expresses the Stephanie Redfern Saylor Fluid

Question 34 / 40: Which of the following expresses the continuity equation (conservation of mass) for an incompressible fluid at steady state?

A $$ \bf{v} = 0$$

B $$ {{\partial \bf{v}} \over {\partial t}} + \nabla \cdot t = 0 $$

C $$\bf{\nabla \cdot v} = 0$$

D $$ {{\partial \rho} \over {\partial t}} + \bf{v} = 0 $$

Explanation:

See subunit 3.1. Start with the full continuity equation. The time derivative is zero and density is a constant (so one can divide the equation by ρ).
