Drip-catcher
The teapot effect, also known as dribbling, is a fluid dynamics phenomenon that occurs when a liquid being poured from a container runs down the spout or the body of the vessel instead of flowing out in an arc. Markus Reiner coined the term "teapot effect" in 1956 to describe the tendency of liquid to dribble down the side of a vessel while pouring. Reiner received his PhD at TU Wien in 1913 and made significant contributions to the development of the study of flow behavior known as rheology. Reiner believed the teapot effect could be explained by Bernoulli's principle, which states that an increase in the speed of a fluid is always accompanied by a decrease in its pressure. When tea is poured from a teapot, the liquid's speed increases as it flows through the narrowing spout. This decrease in pressure was what Reiner thought to cause the liquid to dribble down the side of the pot. However, a 2021 study found the primary cause of the phenomenon to be an interaction of inertia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluid Dynamics
In physics 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 liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves the calculation of various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time. ...

The Daily Telegraph
''The Daily Telegraph'', known online and elsewhere as ''The Telegraph'', is a national British daily broadsheet newspaper published in London by Telegraph Media Group and distributed across the United Kingdom and internationally. It was founded by Arthur B. Sleigh in 1855 as ''The Daily Telegraph & Courier''. Considered a newspaper of record over ''The Times'' in the UK in the years up to 1997, ''The Telegraph'' generally has a reputation for high-quality journalism, and has been described as being "one of the world's great titles". The paper's motto, "Was, is, and will be", appears in the editorial pages and has featured in every edition of the newspaper since 19 April 1858. The paper had a circulation of 363,183 in December 2018, descending further until it withdrew from newspaper circulation audits in 2019, having declined almost 80%, from 1.4 million in 1980.United Newspapers PLC and Fleet Holdings PLC', Monopolies and Mergers Commission (1985), pp. 5–16.

Physics Of Fluids
''Physics of Fluids'' is a monthly peer-reviewed scientific journal covering fluid dynamics, established by the American Institute of Physics in 1958, and is published by AIP Publishing. The journal focus is the dynamics of gases, liquids, and complex or multiphase fluids—and the journal contains original research resulting from theoretical, computational, and experimental studies. History From 1958 through 1988, the journal included plasma physics. From 1989 until 1993, the journal split into ''Physics of Fluids A'' covering fluid dynamics, and ''Physics of Fluids B,'' on plasma physics. In 1994, the latter was renamed ''Physics of Plasmas'', and the former continued under its original name, ''Physics of Fluids''. The journal was originally published by the American Institute of Physics in cooperation with the American Physical Society's Division of Fluid Dynamics. In 2016, the American Institute of Physics became the sole publisher. From 1985–2015, ''Physics of Fluids'' pub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melitta
Melitta () is a German company selling coffee, paper coffee filters, and coffee makers, part of the Melitta Group, which has branches in other countries. The company is headquartered in Minden, North Rhine-Westphalia. It is named after Melitta Bentz (1873–1950) who founded the company after she invented the drip brew paper coffee filter (German patent granted July 8, 1908). Bentz later ran the company as a family business. History In 1908, Melitta Bentz, a 35-year-old woman from Dresden, Germany, invented the first coffee filter, receiving a patent registration for her "Filter Top Device lined with Filter Paper" from the Patent Office in Berlin on July 8. She founded the company bearing her name the same year. In the 1930s, Melitta revised the original filter, tapering it into the shape of a cone and adding ribs. This created a larger filtration area, allowing for improved extraction of the ground coffee. In 1936, the widely recognised cone-shaped filter paper that fit ...

Alcock, Lindley & Bloore Ltd
Samuel Alcock (1799–1848) was a leading English pottery manufacturer who operated as Samuel Alcock & Co in Burslem, Staffordshire from 1828 to 1859. They were especially noted for "picture jugs" modelled and moulded in relief in various ceramic materials, a popular type of object in these years. Samuel Alcock & Co. Alcock was born in Kingsley, Staffordshire. He was the youngest of the nine children of Thomas (1746–1816) and Catherine Alcock (1756–1838). Though from a farming background, he developed an interest in commerce after working with his uncle Joseph Locker, a grocer, tea dealer, provision dealer, chandler and banker of the Market Square, Hanley. His introduction to pottery came when he embarked upon a partnership with Ralph Stevenson of Cobridge, Staffordshire. In 1828, Alcock developed his own business and began work on the Hill Top site in Cobridge. By the 1830s Stevenson employed 600 people at his works. In 1839 he completed work on a large factory, built in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
