- Abstract
Irrigation is an artificial process of application of water in the soil in order to provide the ideal conditions for your crops development. In this sense this study aimed to evaluate a system of irrigation by dripping, working under five different service pressures. The experiment was conducted in an area belonging to the Engineering Laboratory of irrigation and drainage (LEID) of Universidade Federal de Campina Grande (UFCG), located in the municipality of Campina Grande-Paraiba. For system performance analysis were analyzed the following coefficients, Uniformity of Distribution coefficient (CUD), Statistical Uniformity coefficient (Us), coefficient of variation of manufacturing (CVf) and efficiency (Ea), to the pressures of 70, 100, 150, 200 and 250 kPa, respectively.For the coefficients evaluated the treatment using the working pressure of 250 kPa presented the best results. The CUD, values for the five studied service pressures were above 90%, being classified as excellent. The Fvc Middle reached 6.74% value, being within the range of excellence set by the Brazilian Association of technical standards (ABNT). The Us was 93.15% average obtained showing that more than 90% of the data were considered excellent. And the values of Ea to the five studied service pressures reached values greater than 80%, being classified as a satisfactory system. To relate the results to the technical information provided by the manufacturer these demonstrated proximity and may be considered to be acceptable according to the bibliographies of the area.
