Recently in agricultural field, the growth of the coconut tree is affected by harmful insects. This attacks the mainly on outer layer of coconut. In order to reduce the effect various methods are employed. But in our project spraying equipment such as spraying nozzle is used.
A spray nozzle is a device that facilitates the formation of spray. When a liquid is dispersed as a stream of droplets, it is called a spray. Spray nozzles are used to achieve two primary functions: increase liquid surface area to enhance evaporation, or distribute a liquid over an area.
Spray nozzles are used to distribute and disburse insecticides and pesticides including water efficiently in fields. The spray nozzle utilizes the liquid pressure as the energy source to break the liquid into droplets.
This type of spray is less energy consuming than a gas atomized or twin-fluid spray nozzle. As the pressure increases the flow increases and the drop size decreases. But this leads to problems in selecting a droplet size and to achieve a certain flow rate at a given pressure.
To overcome this situation a special nozzle has been developed.
This nozzle can vary the liquid flow rate at a particular droplet size and pressure. This nozzle creates a better and optimum control on the liquid spray and in certain applications can eliminate the need of expensive compressed air.
In agriculture, a sprayer is a piece of equipment that applies herbicides, pesticides, and fertilizers to agricultural crops. Sprayers range in size from man-portable units.
