Drop Size Distributions for a Low Pressure Spray Type Agricultural Sprinkler

ABSTRACT DROPLET distributions are presented for a 360 deg spray nozzle with nozzle sizes ranging from 4.8 to 9.5 mm and pressure ranging from 50 to 200 kPa. Smooth and serrated spray plates were also used. The geometry of the spray plate surface is the dominant parameter that influences drop size distribution when compared to nozzle size and water pressure. The smooth plate produced the smallest droplets and the coarse grooved plate produced the largest.
