Dissertation note: Project paper (Bachelor of Chemistry Engineering ) -- Universiti Malaysia Pahang - 2009 Abstract: Drag is the force that resists the movement of a solid object through a fluid (a liquid or gas). As the point to solve the matter, drag reduction is introduced. Drag reduction can reduce the energy loss and pressure drop in the pipe. As the result, it can reduce of using power to transfer the fluid and save the cost. There are many drag reducing agents (DRA) that can use nowadays. Chitosan is one of the polymers DRA which is biodegradable and have high potential to reduce the drag into 70%. Chitosan is made from the nature that safe to use such as shells of shellfish such as crab and shrimp. The variable is manipulated according to the subject studied. The variables that take part are pipe diameter, pipe length (testing point distance), flowrate, and concentration of the DRA use. The chitosan is prepared with 2%, 4% and 6% of acetic acid addition and the concentration that use in this experiment is 200ppm, 400ppm, 600ppm and 800ppm. Pipeline diameter that used is 0.5 inch, 1.0 inch and 1.5 inch and the pipe length is 0.5 m, 1.0 m, 1.5 m and 2.0 m. The medium that use to perform drag reduction is created for each variable can take place. Raw water is use and the pressure drop of raw water without additive is taken. The concentration is tested one by one and the pressure drop is taken for each concentration. The obtained data is analyzed and the result showed the percentage of drag reduction (%DR) is increase with increase the concentration.
