A water line with an internal radius of 5.06 x 10-3 m is connected to a shower head that has 12 holes. The speed of the water in the line is 1.18 m/s.
(a) What is the volume flow rate in the line?
(b) At what speed does the water leave one of the holes (effective hole radius = 5.38 x 10-4 m) in the head?
