Dissertation note: Project paper (Bachelor of Chemical Engineering) -- Universiti Malaysia Pahang – 2009 Abstract: Fluids are very common and widely used in various industry processes. The only way to transfer fluids is to use pipe. During the transfer, the turbulent flow in pipe always causes a phenomenon called drag. However, this effect could be reduced by addition of Drag Reduction Agents (DRA’s). This study is aimed to provide a clear understanding of the effects of various pipe lengths and pipe diameter on the percentage of drag reduction based on experimental work. In this work, an anionic surfactant, Sodium Dodecyl Sulfate (SDS) will be used as a DRA’S to investigate the purpose as stated above. An experimental apparatus consisting of two tanks, pump, pressure drop indicator, flow meter, test specimen pipe and piping network are set up. The parameters of investigation include concentration of the additive (100, 300 and 500 ppm), different pipe lengths (0.5, 1.0, 1.5, and 2.0 m) as well as different pipe diameters (0.5, 1.0, 1.5 in) at different water flow rates. Through the equivalent altered scale, some interesting results may be discovered.
