Qualidade de irrigação de um microaspersor em diferentes altura de instalação e velocidade média de vento na região do Vale do Curu.

Abstract

To study irrigation quality of a microsplinkles, an experimental set up was alone at the “Fazenda Experimental da UFC ” , at Pentecoste-Ce, Brazil. Comprising a 6m x 12m spacing, 3 different rises heights and 3 average wind velocities. For the mean wind velocity of 2,58m/s the values of CUC (Cristiansen’s Uniformity Coefficient) and CUD (Uniformity of Distribution Coefficient), were above 80%, independing of rises height and indicating a good water distribution. Irrigation efficiency values above 70% were found for rises heights of 0,3 and 1,0m, and should be indicated for mean wind velocities up to 2,58m/s, with application water losses below 30%, as recommended by the literature.
