DC current flows in a metal piece of non-uniform cross-section. Which of these quantities remains constant along the conductor current, current density or drift speed? and Why?

A liquid is flowing in a horizontal pipe of uniform cross section at a speed v. Two tubes A an B are inserted into the pipe as shown. Assume the flow to remain streamiline inside the pipe. (a) The diagram depicts that height of liquid in tube B (=h_(2)) is more than the height of liquid in tube A(=h_(1)) is it correct? (b) Calculate the difference in height of the liquid in two tubes.
