Question: Obtain an equation for the drag on the walls of the
pipe by solving problem 1 below. Show all work
1. The one-dimensional fully developed velocity profile for water flowing through a pipe is given by equation (1): u(r) = Umax (1) (1) where Umax is the maximum flow velocity, R is the radius of the pipe, and r is the radial distance measured from the center of the pipe. Obtain an equation for the drag on the walls of the pipe (20 points)
