1.2. An incompresible fuid fows in a pipe of radius R. At the inlet, sec- tion 1, the velocity is uniform over the tion 2, where the flow is laminar and fully developed, the velocity varies with adius according to the relation V=Vmax (1-R2 (a) Demonstrate that V/Vmax t iu is the average wall shearing stress retarding the flow between see- and 2, fiad the pressure drop (Pl - P) in terms of Vma, p, L, r and F ns PROB. 1.2
