The measurement of droplet size from agricultural nozzles is affected by many factors which require sampling for conditions representative of the application being studied. On orchard airblast sprayers, atomization occurs front nozzles in an airstream primarily by air shear as the liquid meets a high-speed airflow. In the present study, the droplet size spectra from several nozzles were measured in air flows with velocity of 8 and 30 m/s. Two flat fan air-induction nozzles (Albuz AVI 11001 and AVI 8001), and two hollow cone swirl nozzles (non-air induction Albuz ATR lilac, and air induction TVI 800075) were tested at 600 kPa spray pressure. D-v0.1 D-v0.5, and D-v0.9 were compared for these nozzles and ASAE standard S572. One-droplet-size classification classes were determined. Also, relative span, and the relatively highly driftable fraction of spray (<100 mu m) were calculated. Additional fractions <150 mu m (susceptible to drift), 100 divided by 250 mu m (optimal to spraying) and >500 mu m (susceptible to ground losses) were calculated and compared. The measured droplet size values for the nozzles varied under different test conditions, sometimes with a change in the ASABE classification category.
