The fountain refers to the spring water sprayed out of the ground from the ground, especially the artificial water spray equipment, including indoor fountain lights, fountain heads nozzles and so on. A fountain is a combination of a specific shape that sprays water or other liquids through a dancing fountain nozzle under a certain pressure. The water pressure is generally provided by a water pump.
The principle of the fountain is the conservation of momentum. From a large-radius pipeline to a small-radius pipeline, a speed change is produced, rushing in a direction away from the ground. The speed in the large radius is driven by the pump, and the speed in the small radius is the original speed, which transforms the speed together with the momentum. It is necessary to select a micro element to calculate the conservation of momentum, so that a velocity can be obtained, and this velocity is the exit velocity. Then there is an upswing movement. This is an ideal situation, with no air friction and no wind.
