Title: Friction factor for newtonian and non-newtonian fluid flow in curved pipes.
Abstract:The present work deals with the study of laminar and turbulent flow of Newtonian and non-Newtonian fluids flowing through helical and Archimedian spiral coils.

By using a suitable viscosity expression corresponding to the shear stress prevailing at the wall, Newtonian correlations are shown to be applicable to a non-Newtonian fluid also. Relationships for spiral coils are developed from correlations for helical coils and are successfully compared with the data of Newtonian and non-Newtonian fluids.Read More
