Inadequacy of mean hydraulic radius for laminar flow (a) For laminar flow in an annulus with radii

Question:

Inadequacy of mean hydraulic radius for laminar flow

(a) For laminar flow in an annulus with radii kR and Rr use Eqs. 6.2-17 and 18 to get an expression for the average velocity in terms of the pressure difference analogous to the exact expression given in Eq. 2.4-16.

(b) What is the percentage of error in the result in (a) for k = ½ ?
