A water line with an internal radius of 6.21 x 10 -3 m is connected to a shower

Question

A water line with an internal radius of 6.21 x 10-3 m is connected to a shower head that has 13 holes. The speed of the water in the line is 2.74 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 = 5.43 x 10-4 m) in the head?
