Resumo: | The aim of this study was to analyze water application uniformity and wetness pattern of microsprinklers DAN 2001 and DAN 2002 according to ABNT NBR (2004). The test was conducted in Paulista State University, campus of Jaboticabal, SP. The test time was 1 hour under a constant pressure of 250 kPa and total absence of wind, with 3 replications. The distribution uniformity coefficient (CUD); uniformity (CUC) and wetness pattern of microsprinklers were determinated. The average values of CUC for both microsprinklers were described as good, reaching 80.22 and 83.21% for the DAN 2001 and DAN 2002, respectively. The average values of CUD were 71.35% (DAN 2001) and 75.39% (DAN 2002), both described as good. The average values of CUC and CUD did not differ in Tukey tests (p≥0.05), with coefficient variation values of 6.52 and 10.77, respectively. The wetness pattern showed higher intensities application (4.0 to 5.0 mm h-1) for the first 0.25 m distance from the microsprinklers, decreasing with increasing distance, with intensities from 2.0 to 3.0 mm h-1 at 2.25 m. |
