Avaliação de um sistema de irrigação por tubos perfurados.

Abstract

It was characterized the hydraulic performance of a drip irrigation perforated pipe system with round orifices. According to the results, the orifices tested with different service pressures presented low values for the flow rate variation coefficient, that is, about 6.8% (<10%), wich is considered a satisfactory value for emitter average flow rates. The application uniformity showed a great vaiation with changes in service pressure and the highest value obtained for the Christiansen’s coefficient was 52.4%
