After research in the literature dealing with drag reduction phenomena, there was no evidence that aloe Vera was used as flow improver before this in the drag reduction field. Aloe Vera mucilage with concentration from 100 to 400ppm was tested in 2 different internal diameters (0.0254m and 0.0381m) pipes and 5 different flow rate which are represented by Reynolds number. All the experimental work was carried out in a built-up closed loop liquid circulation system with four testing sections of 2m long pipe were investigated. The experimental results showed that the drag reduction increases corresponding with increasing of Re, additive concentration and pipe length and reduction of pipe diameter. The results show, aloe Vera polymer can perform as a good drag reducing agent with maximum percentage drag reduction of 71% obtained at I.D 0.0254m and 15472.694 of Reynolds number for 400ppm of solution. 0aFrictional resistance (Hydrodynamics) 0aPipesxHydrodynamics 0aMucilage
