The flat spray jet is tapered at the ends to guarantee even and uniform fluid coverage also when there are overlapping sprays one adjacent to the other. The impact of the jet is medium to high depending on the angle and the operating pressure.

In this experiment investigating about agricultural sprayers, several methods are used to obtain information. Practically, the experiment is required to calculate the volume of liquid or weedicide mixture required to cover a 1-ha area by using information such as the 5% percentage of concentration of liquid which is 5ml of liquid in a 1 litre bottle and estimation that this sprayer covers 20 km/hr.

Therefore, students measure the volume of water flows out through the nozzle by using measuring cylinder for 5 seconds. Data obtained were then used to calculate the volume of liquid or weedicide needed.

Sprayers are commonly used on farms to spray pesticides, herbicides, fungicides, and defoliants as a means of crop quality control. Invention of sprayer improves the quality of agriculture. They are easy to operate, maintain and handle and facilitates uniform spread of the chemicals.
