ABSTRACT
Measurements were made of the droplet size for a series of air induction flat fan nozzles produced by Marian Mikołajczak
Agro Technology (MMAT) and Coorstek. The MMAT nozzles, according to International Organization for Standardization (ISO)
standard sizes, are typical single jet (long body, 37 mm) with 025, 03, and 04 orifice sizes; (short body, 21 mm) with 02, 025, 03 and
04 orifice sizes; and twin jet (short body, 21 mm) with 03 and 04 orifice sizes. Ceramic air induction flat fan nozzles of the Albuz AVI
series (Coorstek, France) with the orifice size 01, 02 and 03 were tested. The sprays were described using the following droplet size
parameters: D
v10, D
v50, D
v90, relative span (RS), spray volume (%) in size fractions < 100 μm and 100÷200 μm. The sprays were also
classified according to American Society of Agricultural Engineers (ASAE) standard S572.1 (ASAE 2009).
