For one dimensional flow of an incompressible fluid in unsteady state in x-direction, the continuity equation is given by

A $$\frac{{\partial {\text{u}}}}{{\partial {\text{x}}}} = 0$$
B $$\frac{{\partial \left( {\rho {\text{u}}} \right)}}{{\partial {\text{x}}}} = 0$$
C $$\frac{{\partial {\text{u}}}}{{\partial {\text{x}}}} = - \frac{{\partial \rho }}{{\partial {\text{t}}}}$$
D $$\frac{{\partial \rho }}{{\partial {\text{t}}}} = 0$$

Correct Answer: $$\frac{{\partial {\text{u}}}}{{\partial {\text{x}}}} = 0$$
