3. An aqueous solution with a specific gravity of 1.12 flows through a channel with a variable crosssection. Data taken at two axial positions in the channel are shown here. Point 2 is 6.00 meters higher than point 1 . (a) Neglecting friction, calculate the velocity at point 2 . (b) If the pipe diameter at point 2 is 6.00cm, what is the diameter at point 1 ? 3.
