(a) A laminar pipe flow is described by a parabolic velocity profile. The fluid has viscosity µ and a density ρ. The coordinate y is measured from the centerline of the pipe. The velocity profile is described by where R is the pipe radius and is the average velocity. Find the viscous stress at the wall τw and express it non-dimensionally in terms of a skin friction coefficient and the Reynolds number based on diameter and average velocity.
