Question

Write the differential form of continuity equation for two-dimensional steady flow of incompressible fluid.

Answer 1

Hi the differential form of continuity equation for steady 2D flow is
$\frac{du}{dx} + \frac{dv}{dy} = 1$
(Please understand that the derivatives are partial derivatives. I couldn't not find the appropriate symbol for it)
u and v are velocity components in x and y directions respectively.
