Efeito da entrada superior em reservatórios de jusante durante transitório hidráulico em adutoras de distribuição de água

Abstract

This paper aims to evaluate the effect of pipeline connecting through top inlet of downstream reservoirs during hydraulic transients. The method adopted is based on the equations of Soares, Covas and Ramos (2013) and also the unsteady friction factor model of Vítkovský et al. (2000). In order to show the results, the model was implemented into module 7 of System UFC. For validating the model, it was used the data provided by Soares, Covas and Ramos (2013). The obtained results show smaller pressure peaks at the pump section. At the reservoir section, the pressure varies and tends to stabilize at a lower value than that from the previous steady state. Although the classic boundary condition presents a more conservative approach, it does not properly suit the real situation when the pipeline connects through the top inlet of downstream reservoirs, so the latter is more suitable for maintenance and operation of hydraulic systems that are designed this way.
