An aqueous solution with a specific gravity of 1.12 flows through a channel with a variable cross section, 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 6.00 cm, what is the diameter at point1? Point 1= P(gauge)= 1.5 x 10^5pa and u=5m/s point 2= P(gauge)= 9.77 x 10^4pa and u=?
