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.
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.
A satellite image of circular fields characteristic of center pivot irrigation, Kansas Farmland with circular pivot irrigation. Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.
An impact sprinkler head in action Sprinklers spraying water to irrigate vine plants in a vineyard. An irrigation sprinkler (also known as a water sprinkler or simply a sprinkler) is a device used to irrigate (water) agricultural crops, lawns, landscapes, golf courses, and other areas. They are also used for cooling and for the control of ...
He was also an engineer, mathematician and an irrigation and consulting engineer. [2] [3] It was there where Carpenter began the first organized and systematic college program for irrigation engineering starting in 1888. Those completing such instruction were awarded a bachelor of science degree in irrigation engineering. [4] [5] [6]
Control mode sprinklers are intended to control the heat release rate of the fire to prevent building structure collapse, and pre-wet the surrounding combustibles to prevent fire spread. The fire is not extinguished until the burning combustibles are exhausted or manual extinguishment is effected by firefighters.
Rainbird, colloquial name given to various birds thought to sing or come before rain, including the European green woodpecker, Jamaican lizard cuckoo, Jacobin cuckoo, Pacific koel, channel-billed cuckoo, Burchell's coucal and black-faced cuckoo-shrike, as well as certain swifts whose movements are thought to signal the coming of rain
A semi-circular bund (also known as a demi-lune or half-moon) is a rainwater harvesting technique consisting in digging semi-lunar holes in the ground with the opening perpendicular to the flow of water.
