The aim of this paper is to derive the relation between friction factor and the Reynolds number for the pseudo-plastic fluid flow in concentric annular tubes with roughness, which is assumed the model of drilling mud flow in a well, because the estimation methods of the friction factor in the fluid flow are needed.<BR>Based on the estimation methods of the friction factor of Newtonian fluid flow in a circular tube with roughness given by Colebrook and the relation between friction factor and the Reynolds number for the pseudo-plastic fluid flow in a circular tube with smooth wall given by Dodge and Metzner, the relation between friction factor and the Reynolds number for the pseudo-plastic fluid flow in concentric annular tubes with roughness, is obtained as Eq.(21) that is capable of calculating the friction factor in the turbulent flow region of pseudo-plastic fluids in concentric annular tubes with roughness at any values of rheology parameter, relative roughness and Reynolds number by using the subroutine subprogram shown in the appendix.<BR>The relation presented here includes the cases of Newtonian fluid and pseudo-plastic fluid flow in the circular tubes.
