Investigation of the regularity of sedimentation of liquid droplets during field crop spraying

Purpose. Improving the quality of spraying field crops, reducing losses of chemicals of spraying and improving the environmental safety. Methods. Analytical and experimental. Results. Analytical dependences are obtained, which make it possible to determine the droplet velocity depending on their diameter and working pressure. Conclusions. With increase in diameter of the droplet and the liquid pressure in the spray increases the time during which it reaches the speed of hovering and increases the path which will pass a drop until its speed reaches the hovering velocity. These data can be used to justify the rational parameters of the sprayer. Keywords: dispersion of spray, meteorological factors, spraying, droplet settling, spray, rate hovering.
