Irrigation sprinklers are used on farms, golf courses, residential yards, and other places to water crops, lawns, gardens or other plants in the event of drought. Irrigation is an artificial application of water to the soil usually for assisting in growing crops Agriculture refers to the production of goods through the growing of plants and fungi and the raising of domesticated Animals The study of agriculture A lawn is an area of recreational or amenity land planted with grass, and sometimes Clover and other plants which are maintained at a low even height A garden is a planned space usually outdoors set aside for the display cultivation and enjoyment of Plants and other forms of Nature. A drought is an extended period of months or years when a region notes a deficiency in its water supply They are also used for recreation or as a cooling system.
Sprinklers that spray in a fixed pattern are generally called sprays or spray heads. Sprays are not usually designed to operate at pressures above 30 lbf/in² (200 kPa), due to misting problems that may develop.
Higher pressure sprinklers that rotate around themselves are driven by a ball drive, gear drive, or impact mechanism (impact sprinklers). An Impact sprinkler (sometimes incorrectly called an impulse sprinkler) is a type of Irrigation sprinkler used primarily to irrigate farm fields These can be designed to rotate in a full or partial circle.
Some sprinklers are also known as Floppy Sprinkler, Spray Pop-ups, pulsating sprinklers due to their water stream and revolutionary new concept having no rotating or moving parts.
Rainguns are similar to impact sprinkler, except that they generally operate at very high pressures of 40 to 130 lbf/in² (275 to 900 kPa) and flows of 50 to 1200 US gal/min (3 to 76 L/s), usually with nozzle diameters in the range of 0. 5 to 1. 9 inches (10 to 50 mm). In addition to irrigation, guns are used for industrial applications such as dust suppression and logging. Dust is a general name for minute Solid particles with Diameters less than 500 micrometers. Logging is the process in which Trees are cut down for Forest management and Timber.
Many irrigation sprinklers are buried in the ground along with their supporting plumbing, but above ground and moving sprinklers are also common. Most irrigation sprinklers are functioned through electric and hydraulic technology and are grouped together in zones that can be collectively turned on and off by actuating a solenoid-controlled valve. A solenoid is a three-dimensional Coil. In Physics, the term solenoid refers to a loop of wire often wrapped around a Metallic core which

Underground sprinklers (generally used for high-end home lawns and gardens) function through means of basic electronic and hydrolic technology. A 110 volt supplied controller, or sprinkler box sends a pre-determind 24 volt signal to an awaiting solenoid valve buried in the yard. This valve and all of the sprinklers that will be activated by this valve are known as a zone. Upon activation, the solenoid, which sits on top of the valve is magnetized lifting a small stainless steel plunger in its center. By doing this, the activated (or raised) plunger allows air to escape from the top of a rubber diaphragm located in the center of the valve. Water that has been charged and waiting on the bottom of this same diaphragm now has the higher pressure and lifts the diaphragm. This pressurized water is then allowed to escape down stream of the valve through a series of PVC pipes. Along these pipes and flush to grade level are pre measured and spaced out sprinklers. These sprinklers can be fixed spray heads that have a set pattern and generally spray between 7 and 15 feet, full rotating sprinklers that can spray a broken stream of water from 20 to 40 feet, or small drip emitters that release a slow, steady drip of water on more delicate plants such as flowers and shrubs.
Most irrigation sprinklers are used as part of a sprinkler system, consisting of various plumbing parts, piping and control equipment. Piping is connected to the water source via plumbing fittings and the control system opens and closes valves to provide water on a schedule. The control provided varies depending on the equipment used; some systems are fully automated and even compensate for rain, runoff and evaporation, while others require much more user attention for the same effectiveness.
