Spray atomization can be formed by several methods. The most common method is through a spray nozzle which typically has a fluid passage that is acted upon by different mechanical forces that atomize the liquid. [3] The first atomization nozzle was invented by Thomas A. DeVilbiss of Toledo, Ohio in the late 1800s. His invention was a bulb ...
Aerial video of a sprayer (unfolding and driving) A sprayer is a device used to spray a liquid, where sprayers are commonly used for projection of water, weed killers, crop performance materials, pest maintenance chemicals, as well as manufacturing and production line ingredients.
A wide variety of spray nozzles exist, that make use of one or multiple liquid breakup mechanisms, which can be divided into three categories: liquid sheet breakup, jets and capillary waves. Spray nozzles are of great importance for many applications, where the spray nozzle is designed to have the right spray characteristics. [1]
The spray generated by a device like a rotary atomizer can be viewed as liquid droplets submerged in a continuous phase of gases. The size of droplet formed by atomizer depends on various properties of the fluid (both liquid and gaseous fluid) such as density, viscosity and surface tension between fluids. Generally, small gas turbines operate ...
While spray bottles existed long before the middle of the 20th century, they used a rubber bulb which was squeezed to produce the spray; the quickly-moving air siphoned fluid from the bottle. The rapid improvement in plastics after World War II increased the range of fluids that could be dispensed, and reduced the cost of the sprayers because ...
The non-clogging nature of ultrasonic nozzles, the small and uniform droplet size created by them, and the fact that the spray plume can be shaped by tightly controlled air shaping devices makeS the application quite successful in wave soldering processes. The viscosity of nearly all fluxes on the market fit well within the capabilities of the ...
The application of the spray drying encapsulation technique is to prepare "dehydrated" powders of substances which do not have any water to dehydrate. For example, instant drink mixes are spray dries of the various chemicals which make up the beverage. The technique was once used to remove water from food products.

Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
