  2. Matched precipitation rate - Wikipedia

    en.wikipedia.org/wiki/Matched_precipitation_rate

    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 ...

    Newer systems have drop sprinkler heads as shown in the image that follows. As of 2017 most center pivot systems have drops hanging from a U-shaped pipe attached at the top of the pipe with sprinkler heads that are positioned a few feet (at most) above the crop, thus limiting evaporative losses. Drops can also be used with drag hoses or ...

  7. Impact sprinkler - Wikipedia

    en.wikipedia.org/wiki/Impact_sprinkler

    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.

  8. Micro-irrigation - Wikipedia

    en.wikipedia.org/wiki/Micro-irrigation

    Low volume micro-sprinklers or high-efficiency nozzles may be attached to hard plastic risers or attached to standard sprinkler heads, but are also mounted on stakes and attached to small diameter micro-tubing connected to polyethylene tubing with a barbed connector. Some micro-sprinklers have a fixed spray or stream pattern, while others rotate.
