The velocity profile in fully developed laminar flow in a

Question

Question: The velocity profile in fully developed laminar flow in a circular pipe, in m/s, is given by u(r) = 6(1 - 100r²) where r is the radial distance from the centerline of the pipe in m. Determine

(a) the radius of the pipe,

(b) the mean velocity through the pipe, and

(c) the maximum velocity in the pipe.
