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.

Units and Dimensions

Dimensions are the basic concepts of the measurement of quantities. Units are the means of expressing the dimensions. For instance, an area has a dimension of L2 and a unit of m2.
