Continuity equation for incompressible, steady, two dimensional flow - Heat Transfer

Q.  Consider the flow of fluid in a boundary layer. Take a control volume which has a shape of a parallelopiped with dimensions (dx x dy x 1)
u = velocity of the fluid entering the control volume
v = velocity of the fluid leaving the control volume

Considering above condition, the equation

(∂u / ∂x) + (∂v / ∂y) = 0

is known as
