New equation calculates friction factor for turbulent flow of non-Newtonian fluids

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. Click here to enlarge imageThe 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 the literature. The present research ...
