Diseño y modelado hidráulico de un banco de pruebas utilizando el software epanet para realizar prácticas experimentales en conductos forzados

Abstract

The work carried out is intended to be used as a reference for the construction of a physical model, for this purpose a test bench was hydraulically modeled, a pumping system and a board with 4 pipe branches were implemented to verify the hydraulic behavior of the pipes, which allows to determine the pressure losses due to friction and accessories with the help of EPANET software, the purpose is that later a test bench can be made available in the laboratory, so that the students of the Civil Engineering career of the Technical University of Machala can carry out their Piping Hydraulics practices. The test bench was designed with four branches of pipes of different diameters, in which water will circulate driven by a centrifugal pump and will return to the tank where it will be pumped again forming a closed circuit. To measure the flow, a digital water flow measuring device with a sensor was installed, a regulation valve was installed at the beginning of the pipe to control the water flow, the pressure will be measured with a pressure nanometer consisting of a tape measure attached to the board, an air valve was also installed at the critical point of the system to allow the expulsion of air bubbles in the pipes when the flow starts. Analytical calculations were made and with the help of EPANET the hydraulic behavior in the pipes was verified, in addition the pressures and flows in the system were also identified.
