Influencia do canhão final na distribuição de pressão e vazão da linha lateral de um pivô central

Abstract

The aim of this work was to analyze the influence of the presence of the end gun, with different flow rates, on the pressure distribution and lateral line flow of a center pivot irrigation system using the EPANET hydraulic simulator compared to an analytical model. Simulations were performed on center pivot lateral line located in Lavras/MG. In the simulations was inserted an end gun operating under high flow. There was also decrease lateral line diameter aiming to cause greater head loss. The results obtained were compared with the use of EPANET parameters and with an analytical method. Thus, this study showed the influence from flow increase in the pressure distribution of the pivot lateral line, since there was an end gun in the end of the lateral. The results also demonstrated a satisfied estimative of EPANET's hydraulic theory.
