Irrigation system with ultra low flow using branched microtubes
Abstract With the goal of developing an irrigation system with ultra low flow rate (ULF) of 0.2 L h-1, using microtubes with derivation and operating in a laminar regime, this work began by seeking efficient irrigation and low costs. The experiment consisted of two stages. The first experiment was conducted in the laboratory to determine the actual diameter of the microtubes and irrigation system design. The second stage of the experiment was conducted in an experimental area, where tests were carried out to obtain the uniformity of water application which was evaluated by the coefficient of uniformity statistic that had an initial value exceeding 90%. The proposed irrigation system had economic advantages for small-scale producers. However, the system evaluated presented problems with accumulation of air and emitters obstruction during the study period, causing a reduction in statistical uniformity. It is therefore necessary to conduct further studies to obtain more conclusive results.
