Water ?ows in a 2-cm-diameter pipe at 10 m=s vertically upward to the center of two horizontal circular disks separated by 8 mm. It ?ows out between the disks at a radius of 25 cm. Sketch the pipe/disk arrangement. Calculate average velocity of the water leaving the disks. Also, calculate the average velocity of the water between the disks at a position where the radius of the disks is 10 cm.
