The current study attempts to experimentally determine the effects of nozzle type, size and pressure on spray parameters. A total of 8 even flat fan nozzles were tested at pressures of 2 and 3bar. Spraying pattern analyzing method (pattrenator) was used to measure spray width and distribution. Liquid volume under the nozzle from pattrenator was quantified by weight method using precision electrical balance. The results indicated that DG flat fan nozzle behaviour was to some extent similar to that TP flat fan nozzle but additional variables like increase of spray width. Results also showed that small variations in nozzle pressure can cause significant difference in spray width and spray distribution. The current work presents liquid volume data under the nozzle centre increased with increasing nozzle size.
