ESTUDIO DE LAS VARIACIONES DE PRESIÓN EN REDES DE DISTRIBUCIÓN DE AGUA POTABLE POR PÉRDIDAS DE FRICCIÓN, APLICADA EN EL DIMENSIONAMIENTO DE LAS REDES DE LA COMUNIDAD CHACRAS ADENTRO DE LA PARROQUIA RURAL RIOCHICO

Abstract

This research develops the design of the distribution networks of drinking water Chacras Adentro community Riochico rural parish where a comparative analysis of the results is done by applying models of Darcy-Weisbach, Hazen -Williams and Manning in order to determine changes that occur in the system pressure by frictional losses that arise regarding the model employed. Prior to the design of this system information was collected through interviews, made the president of the community and professionals familiar with the matter, as well as surveys of people in the community to establish the socioeconomic status of the population in general. By using the software they are designed WaterGEMS each of the alternatives involving the study and design of the distribution network of drinking water Chacras Adentro community. The results generated by the software design are analyzed through comparative tables and graphs where pressure variations suffering pipes against the application of either calculation model are described. Likewise an independent design is performed by each method, in order to identify whether the choice of any of them involves variations in costs for pipes, for which the reference budget is attached method. The results set the model Darcy-Weisbach is more efficient in economic and hydraulic aspect and this is mainly because there is no restriction on the application of the formula to the flow as if it occurs with the method of Hazen-Williams is limited to be used in equal or greater than 75mm in diameter and as potable water works with smaller diameter, involves errors in their results.
