The velocity profile in laminar flow through a round pipe is expressed as: υ = 2 U ( 1 − (r^2/r0^2 )   where U is the average velocity, r is the radial distance from the center line of the pipe, and r0 is the pipe radius. [b] Draw the dimensionless shear stress profile τ/τ0 against r/r0 where τ0 is the wall shear stress. [c] Find the value of τ0, when fuel oil having an absolute viscosity of 4 x 10–2 Ns/m2 flows with an average velocity of 4 m/s in a pipe of diameter 150 mm.
