Objectives: The aim of the present work is to study the effect of adding Nano-Al2O3 on the experimental friction factor and pressure drop for Iraqi crude oil. Methods/Statistical Analysis: The effect of three pipe diameters (0.5, 0.75 and 1 inch), five values of Reynolds number and Nano-Al2O3 concentration (0.002–0.01 wt %) on the friction factor were studied. Findings: The results illustrated that the friction factor is generally decreased with increasing of Nano-Al2O3 concentration and crude oil flow rate. Application/Improvements: There is very low available literature on the drag reduction process by using Nano-Al2O3 as drag reduction agent for Iraqi crude oil.
