Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and petroleum products. The accuracy of the proposed equation was checked statistically and by measured and field-calculated data. Turbulent pressure loss due to friction in any pipeline can be calculated only if the friction factor is first determined. Determining this factor poses a significant problem for a pipeline engineer designing for non-Newtonian fluids because of the large number of friction-factor equations available in literature. The present research work set out to compare among the different friction-factor equations and propose an accurate one. The results led to proposal of a regression equation for calculating the friction factor based on the available measured data.
