Question:

In regions far from the entrance, fluid flow through a circular pipe is one dimensional, and the velocity profile for laminar flow is given by u(r) = umax(1 - r2/R2), where R is the radius of the pipe, r is the radial distance from the center of the pipe, and umaxis the maximum flow velocity, which occurs at the center. Obtain

(a) A relation for the drag force applied by the fluid on a section of the pipe of length L and

(b) The value of the drag force for water flow at 20°C with R = 0.08 m, L = 30 m, umax = 3 m/s, and μ = 0.0010 kg/mˆ™s.
