Abstract

Analysis of head loss in pipes is important for effective designing of irrigation systems, because of its influence on pumping system, project cost and energy demand. This study was done to determine the possibility of using polyacrylamide polymer as hydrodynamic friction reducing agent in polyethylene pipes to reduce head loss. The study was conducted at Irrigation Equipment Testing Laboratory of the Rural Engineering Department belonging to Faculty of Agronomic Sciences, Botucatu – SP. The tests were conducted using pipe diameter of 1, 3/4 or 1/2 inch, at the flow rates of 0.352, 0.225, 0.125, 0.05 or 0.0175 L s-1, to simulate the laminar, transition and turbulent flow with the polymer concentration of 10 mg L-1. The head loss reduction reached 76.93% in one inch pipes. The reduction of friction factor was also significant. The data showed that the use of polyacrylamide is feasible considering quantity necessary to obtain satisfactory results.
