Hydrodynamic
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 moment (physics), moments on aircraft, determining the mass flow rate of petroleum through pipeline transport, pipelines, weather forecasting, predicting weather patterns, understanding nebulae in interstellar space and Nuclear weapon design, 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 velo ...

Inland Navigation
Inland navigation, inland barge transport or inland waterway transport (IWT) is a transport system allowing ships and barges to use inland waterways (such as canals, rivers and lakes). These waterways have inland ports, marinas, quays, and wharfs. Environment Modern researchers have long recognised that inland navigation is a relatively environmentally friendly option for freight transport compared to other modes of transportation such as air carriage and road transport, and similar to rail freight transport. Therefore, policy makers have been aiming to shift the volume of cargo transported by more pollutive means towards inland navigation in order to reduce the overall environmental impact of transport, for example, as part of the European Green Deal (2019). To accomplish this, however, various challenges need to be tackled, including making inland navigation itself less pollutive than it has been, building larger barges and tows to increase their efficiency, and construct ...

Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightness ...

Cavitation Tunnel
A water tunnel is an experimental facility used for testing the hydrodynamic behavior of submerged bodies in flowing water. It functions similar to a recirculating wind tunnel, but uses water as the working fluid, and related phenomena are investigated, such as measuring the forces on scale models of submarines or lift and drag on hydrofoils. Water tunnels are sometimes used in place of wind tunnels to perform measurements because techniques like particle image velocimetry (PIV) are easier to implement in water. For many cases as long as the Reynolds number is equivalent, the results are valid, whether a submerged water vehicle model is tested in air or an aerial vehicle is tested in water. For low Reynolds number flows, tunnels can be made to run oil instead of water. The advantage is that the increased viscosity will allow the flow to be a faster speed (and thus easier to maintain in a stable manner) for a lower Reynolds number. Whereas in wind tunnels the driving force is usua ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dutch Guilder
The guilder ( nl, gulden, ) or florin was the currency of the Netherlands from the 15th century until 2002, when it was replaced by the euro. The Dutch name ''gulden'' was a Middle Dutch adjective meaning "golden", and reflects the fact that, when first introduced in 1434, its value was about equal to (i.e., it was on par with) the Italian gold florin. The Dutch guilder was a ''de facto'' reserve currency in Europe in the 17th and 18th centuries. Between 1999 and 2002, the guilder was officially a "national subunit" of the euro. However, physical payments could only be made in guilders, as no euro coins or banknotes were available. The exact exchange rate, still relevant for old contracts and for exchange of the old currency for euros at the central bank, is 2.20371 Dutch guilders for 1 euro. Inverted, this gives 0.453780 euros for 1 guilder. Derived from the Dutch guilder are the Netherlands Antillean guilder (still in use in Curaçao and Sint Maarten) and the Surinamese gui ...

Koninklijke Paketvaart-Maatschappij
Koninklijke Paketvaart-Maatschappij (Dutch for Royal Packet Navigation Company), better known as KPM, was a Dutch shipping company (1888–1966) in the Netherlands East Indies, now Indonesia. It was the dominant inter-island shipping line in Indonesia during the last half century of the colonial era. Before World War II Foundation of the KPM In 1863 the British Nederlandsch-Indische Stoomvaartmaatschappij (NISM) had won a tender for a number of subsidized shipping lines in the Dutch East Indies. As a consequence the inter island shipping lines got centered on Singapore. Furthermore all but two of the many ships required were built in the United Kingdom. The minister of colonial affairs Jacobus Sprenger van Eyk and the businessmen Jan Boissevain (1836-1904), Willem Ruys and P.E. Tegelberg then came up with a plan for a new 'national' shipping line. On 19 March 1888 a law was made to govern the relations between the (Dutch East Indies) government and the new public comp ...

Royal Rotterdam Lloyd
The Royal Rotterdam Lloyd (Koninklijke Rotterdamsche Lloyd or KRL) was a Dutch shipping company that was established in Rotterdam between 1883 and 1970. Until 1947 the name was Rotterdamsche Lloyd (RL). In 1970 the KRL merged with several other Dutch shipping companies to form the Nederlandsche Scheepvaart Unie (NSU), known from 1977 as Nedlloyd. History The ''Royal Rotterdam'' was founded on June 15, 1883 with seven ships, housed in joint shipping companies and under the management of Wm. Ruys & Zonen, were united in one company the company's origins date back to 1839 when the Rotterdam shipowner Willem Ruys (1809-1889) set sail for the Dutch East Indies and the Far East. As a result of the opening of the Suez Canal, his son Willem Ruys (1837-1901) expanded the company in 1872 with a steamboat service to Batavia. In 1875 he founded the Partenrederij Stoomboot Reederij "Rotterdamsche Lloyd" himself, whose name was changed in 1881 to Stoomv ...

Netherland Line
The Stoomvaart Maatschappij Nederland ("Netherlands Steamship Company") or SMN, also known as the Netherland Line or Nederland Line, was a Dutch shipping line that operated from 1870 until 1970, when it merged with several other companies to form what would become Royal Nedlloyd.Nedlloyd itself later merged with Peninsular and Oriental Steam Navigation Company (P&O) to become P&O Nedlloyd, now a part of Maersk. The company's motto, ''Semper Mare Navigandum'' ("Always sail the seas"), conveniently fitted the same initials. Foundation Introduction The SMN was founded on May 13, 1870 in Amsterdam for the trade between North Western Europe and the former Dutch East Indies (modern Indonesia) via the newly opened Suez Canal. Construction of the Suez Canal had started on 25 April 1859. Together with the development of steam engines with lower coal consumption (the compound engine), the realization of a suitable canal would make sailing ships obsolete on the passage to the East I ...

Great Depression In The Netherlands
The Great Depression in the Netherlands ( nl, De Grote Depressie, also called the crisis years: ''de Crisisjaren'', ''de Crisistijd'') occurred between 1933 and 1936,Beishuizen, Jan, & Werkman, Evert (1967) De Magere Jaren: Nederland in de crisistijd, 1929–1939, 2nd edition. Sijthoff, Leiden. significantly later than in most other countries. It was a period of severe economic crisis in the 1930s which affected countries around the world, including the Netherlands. In the United States, the Wall Street Crash of 1929 is understood as the start of the Great Depression. But in the Netherlands the depression started more gradually, in 1929–1931, while the economy had been in a gradual decline for a longer period. In the Netherlands the depression lasted significantly longer than in most countries, partly because of structural characteristics of the Dutch economy and partly because of the policy of the government. The refusal to drop the gold standard plays a central role. The Great ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
