When an aerator is added to the faucet (or fluid stream), there is a region of high pressure created behind the aerator. Because of the higher pressure behind the aerator and the low pressure in front of it (outside the faucet), due to Bernoulli's principle there is an increase in velocity of the fluid flow.
Elie Prodromou Aghnides (1901–1988) was a Greek engineer and inventor, best known for his invention of the faucet aerator. He was born in Istanbul , Ottoman Empire, in 1901. He had three siblings: Nicholas Aghnides, a former professor at Columbia University ; Thanasis Aghnides, a Greek ambassador and undersecretary to the United Nations in ...
An air gap, as related to the plumbing trade, is the unobstructed vertical space between the water outlet and the flood level of a fixture. [1] Air gaps of appropriate design are legally required by water health and safety regulations in many countries. An air gap is the simplest form of a backflow prevention device.
Faucet is the most common term in the US, similar in use to "tap" in British English, e.g. "water faucet" (although the term "tap" is also used in the US). Spigot is used by professionals in the trade (such as plumbers), and typically refers to an outdoor fixture.
In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases.It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).
Price Pfister was founded by Emil Price and William Pfister in Los Angeles [1] in 1910, [2] when the company introduced its first product, a garden faucet. Over the next decade, Price Pfister’s product line expanded to include other types of faucets, valves and hose nozzles for indoor sinks and bathtubs.
The low speed surface aerator is a device for biology aeration with high efficiency. These devices are often in steel protected by epoxy coating and generate high torque. The mixing of water volume is excellent. The common power is going from 1 up to 250kw per unit with an efficiency (SOE) around 2 kgO2/kw.
In wine tasting, a variety of methods are used to aerate the wine and bring out the aromas, including swirling wine in the glass, using a decanter to increase exposure to air, or using a specialized wine aerator. Cider from Asturias is poured into the glass from a height of about 1 metre (el escanciado) to increase aeration.
