| Abstract | ||||
| Accurate pesticide application from sprayers is essential in modern farming practice. Evenness of flow characteristics of liquid from a sprayer nozzle is one of the requirements of accurate pesticide application. Hence, a study aimed to evaluate the flow characteristics of liquid from four different spray nozzles 422HCC02, 422HCC025, 422HCC03, and 422HCC05 on a horizontal spray patternator. The discharge rate, spray distribution pattern, spray swath of all types of nozzles were measured with a pressure range of 6.0 and 9.5 bar at three different nozzle height (30, 40 and 50 cm). The results showed that, Distribution uniformity of spraying machine ranged between (95.88 to 99.17 %), spray overlap varies from 7.5 to 47.5 cm, depending on spraying height and pressure, maximum spray angle was 89.59 ° at 30 cm height and 9.5 bar. Also, the results indicated that maximum spray angle 96.77 when the spraying pressure was 9.5 bar. | ||||
