RESUMO

The objective of this work was evaluate the transversal spray deposition of double plain spurt nozzles TTJ60-11004 and TTJ60-11002 in different operational conditions. Was used five samples of each nozzle and considerate a unite one repetition. The spray deposition was evaluate on a table of evaluation distribution constructed in accordance with norm ISO 5682-1. Was evaluate a single spray distribution, volumetric distribution of the overlapping spurts by means of the coefficient of variation (CV%), outflow and angle of opening of the spurts. The operational conditions had been pressure of work of 200, 300 and 400 kPa, height of 30, 40 and 50 cm in relation to the target and spacing between nozzles in 45 and 100 cm simulated in software (Microsoft Excel). The nozzles presented discontinous individual profile with higher liquid deposition in the central region and gradual volume reduction in direction to extremities. The increase in the pressure promoted along of the profile and the band of application. The nozzles provided profile uniform to depend on the space between nozzles, with lesser values with reduction in the space and higher pressures. The outflow and the angle of the spurt had increased with the increment in the pressure
