This work was carried out at the Department of Agricultural Engineering, Escola Superior de Agricultura "Luiz de Queiroz" (USP/ESALQ), Piracicaba-SP, Brazil. The objective of this research was to study the spray pattern of the flat fan tip (8002) at different spacings between nozzles. Thus, ten nozzles were placed on a tilted foil, one at a time, at a fixed height of 45 cm, with spacings varying from 10 to 80 cm. Nozzle output was collected separately from each nozzle and used to calculate the variation coefficient and determine the more appropriate spacing between nozzles. It was concluded that, 50 cm-spaced flat fan tips (8002) showed the best spray pattern with a smaller variation coefficient at a fixed height of 45 cm and pressure regulated at 279.3 kPa registered in the manometer.
