Irrigation Sprinkler
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 airborne dust. Sprinkler irrigation is the method of applying water in a controlled manner in way similar to rainfall. The water is distributed through a network that may consist of pumps, valves, pipes, and sprinklers. Irrigation sprinklers can be used for residential, industrial, and agricultural usage. It is useful on uneven land where sufficient water is not available as well as on sandy soil. The perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals. When water is pressurized through the main pipe it escapes from the rotating nozzles. It gets sprinkled on the crop. In sprinkler or overhead irrigation, water is piped to one more central locations within the field and distributed by overhe ...

Fire Sprinkler
A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings protected by properly designed and maintained fire sprinklers, over 99% of fires were controlled by fire sprinklers alone. History In 1812, British inventor Sir William Congreve patented a manual sprinkler system using perforated pipes along the ceiling. When someone noticed a fire, a valve outside the building could be opened to send water through the pipes. It was not until a short time later that, as a result of a large furniture factory that repeatedly burned down, Hiram Stevens Maxim was consulted on how to prevent a recurrence and invented the first automatic fire sprinkler. It would douse the areas that were on fire and report the fire to the fire st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sprinkler (dance)
The Sprinkler dance is a form of dance move involving a person placing one hand on the back of the neck, and waving the other arm back and forth while spinning in a circle. This simulates the motion of a garden irrigation sprinkler. Originating in the late disco era of the 1970s around the time of The Bump in Australia, its popularity was revived by the England cricket team during their winning 2010–11 Ashes series competition, and resultantly went viral on the internet by Ron Trubisky Dance steps The movement of the dancers body is meant to replicate the movements of an irrigation sprinkler. Standing with legs slightly apart and knees slightly bent, the dancer then bends their left elbow to enable them to place their left hand behind their head. They then outstretch their right arm inline with their right shoulder, hand flat in a vertical position. The dancer then rotates around the waist in a 180 degree sweep, pulling back three times as you move your arm to the left, and the ...

Feynman Sprinkler
A Feynman sprinkler, also referred to as a Feynman inverse sprinkler or as a reverse sprinkler, is a sprinkler-like device which is submerged in a tank and made to suck in the surrounding fluid. The question of how such a device would turn was the subject of an intense and remarkably long-lived debate. A regular sprinkler has nozzles arranged at angles on a freely rotating wheel such that when water is pumped out of them, the resulting jets cause the wheel to rotate; both a Catherine wheel and the aeolipile ("Hero's engine") work on the same principle. A "reverse" or "inverse" sprinkler would operate by aspirating the surrounding fluid instead. The problem is now commonly associated with theoretical physicist Richard Feynman, who mentions it in his bestselling memoirs ''Surely You're Joking, Mr. Feynman!'' The problem did not originate with Feynman, nor did he publish a solution to it. History The first documented treatment of the problem is in chapter III, section III of E ...
