<b>Abstract.</b> The Generalized Integral Transform Technique (GITT) is employed in the solution of the momentum equations in hydrodynamically developing laminar flow of non-Newtonian power-law fluids inside circular ducts. Results for the velocity field and friction factor-Reynolds number product are computed for different power-law indices, which are tabulated and graphically presented as functions of the dimensionless coordinates. Critical comparisons with previous results in the literature are also performed, in order to validate the numerical codes developed in the present work and to demonstrate the consistency of the final results.
