In order to be "matched" all sprinkler heads in a given zone must have the same rate of precipitation. This can be achieved by matching the gallonage of a standard rotor to its arc and reducing range accordingly (i.e. 2 gallons at 90 degrees, 4 gallons at 180 degrees, or 8 gallons if the head does a full circle) or by using MPR nozzles or ...
Impact sprinkler head. An impact sprinkler (sometimes called an impulse sprinkler) is a type of irrigation sprinkler in which the sprinkler head, driven in a circular motion by the force of the outgoing water, pivots on a bearing on top of its threaded attachment nut. Invented in 1933 by Orton Englehart, it quickly found widespread use.
The Rain Bird horizontal action impact-drive sprinkler head was recognized as a historic landmark of agricultural engineering in 1990 by the American Society of Agricultural and Biological Engineers. [3] This invention led to sprinkler irrigation development that currently exceeds 50,000,000 acres (78,000 sq mi; 200,000 km 2) worldwide.

Rain Clox was the trade name given to a series of electromechanical irrigation controllers produced by the Rain Bird Corporation from 1962 to the late 2000s (decade), and were largely responsible for giving rise to the widespread use of automatic irrigation. The first model was the ME11AB, capable of running 11 stations on two schedules.
A sign warns hotel guests not to hang items from fire sprinklers. Each closed-head sprinkler is held closed by either a heat-sensitive glass bulb or a two-part metal link held together with fusible alloy. The glass bulb or link hold in place a "pip cap" which acts as a plug to prevent water from flowing, unless the ambient temperature around ...
Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles. Calculation
Wetlands help maintain the level of the water table and exert control on the hydraulic head. [ 5 ] [ 6 ] This provides force for groundwater recharge and discharge to other waters as well. The extent of groundwater recharge by a wetland is dependent upon soil , vegetation , site, perimeter to volume ratio, and water table gradient.
