Water flows into a cylindrical pipe, initially with an x-directional velocity vector, U0, that is independent of y and z. As the water travels through the pipe, a laminar flow pattern develops.
Consider the formula for Incompressible Continuity:
why the answer is greater than zero?

x U0
Consider the formula for Incompressible Continuity:
∂u/∂x + ∂v/∂y + ∂w/∂z = 0
At point A, which is on the center line of the pipe, the value of the first term of this equation is:
A) greater than zero.
B) less than zero.
C) zero.
D) impossible to determine.
