Spray (liquid drop)A spray is a dynamic collection of drops dispersed in a gas. The process of forming a spray is known as atomization. A spray nozzle is the device used to generate a spray. The two main uses of sprays are to distribute material over a cross-section and to generate liquid surface area. There are thousands of applications in which sprays allow material to be used most efficiently.Rotary atomizersRotary atomizers use a high speed rotating disk, cup or wheel to discharge liquid at high speed to the perimeter, forming a hollow cone spray. The rotational speed controls the drop size. Spray drying and spray painting are the most important and common uses of this technology. Many industries need to convert a large mass of liquid into a dispersion of small (micron-size) droplets (generate a spray).
Ultrasonic nozzleUltrasonic nozzles are a type of spray nozzle that use high frequency vibrations produced by piezoelectric transducers acting upon the nozzle tip that create capillary waves in a liquid film. Once the amplitude of the capillary waves reaches a critical height (due to the power level supplied by the generator), they become too tall to support themselves and tiny droplets fall off the tip of each wave resulting in atomization.
Surface tensionTendency of a liquid surface to shrink to reduce surface area Rain water flux from a canopy.
Flue-gas desulfurizationFlue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns.
BottleA bottle is a narrow-necked container made of an impermeable material (such as glass, pottery, porcelain, plastic or aluminium) in various shapes and sizes that stores and transports liquids. Its mouth, at the bottling line, can be sealed with an internal stopper, an external bottle cap, a closure, or induction sealing. EtymologyFirst attested in 14th century.

BrassBrass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic, and chemical properties, but copper typically has the larger proportion, generally 2⁄3 copper and 1⁄3 zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, a copper alloy that contains tin instead of zinc.
Stainless steelStainless steel is an iron-based alloy that contains chromium, making it resistant to rust and corrosion. Alternatively, it is known as inox (an abbreviation of the French term inoxydable, meaning non-oxidizable), corrosion-resistant steel (CRES), Nirosta (an abbreviation of the German term nichtrostender Stahl) or rustless steel.
Aerosol spray dispenserAerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. It comprises a can or bottle that contains a payload, and a propellant under pressure. When the container's valve is opened, the payload is forced out of a small opening and emerges as an aerosol or mist. HistoryThere is a high chance that the concepts of aerosol go as far back as 1790.
HerbicideType of chemical used to kill unwanted plantsA field after application of a herbicideWeeds controlled with herbicideHerbicides (US: , UK: ), also commonly known as weed killers, are substances used to control undesired plants, also known as weeds. Selective herbicides control specific weed species while leaving the desired crop relatively unharmed, while non-selective herbicides (sometimes called "total weed killers") kill plants indiscriminately.*As an Amazon Associate I earn from qualifying purchases.
