A Water wheel is a machine for converting falling or flowing water into useful power.

Water wheel machine for converting falling or flowing water into useful power

A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel, with a number of blades or buckets arranged on the outside rim forming the driving surface.

Water wheel or Waterwheel may also refer to:

Paddle steamer steamship or riverboat powered by a steam engine that drives paddle wheels

A paddle steamer is a steamship or riverboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans.

Noria machine activated by water power and used for lifting water into a small aqueduct

A noria is a hydropowered machine used to lift water into a small aqueduct, either for the purpose of irrigation or for the use in towns and villages. There is at least one known instance where it feeds seawater into a saltern.

Watermill structure that uses a water wheel or turbine to drive a mechanical process

A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, wire drawing mills.

Steamship Type of steam powered vessel

A steamship, often referred to as a steamer, is a type of steam powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for paddle steamer or "SS" for screw steamer. As paddle steamers became less common, "SS" is assumed by many to stand for "steam ship". Ships powered by internal combustion engines use a prefix such as "MV" for motor vessel, so it is not correct to use "SS" for most modern vessels.

Steamboat Smaller than a steamship; boat in which the primary method of marine propulsion is steam power

A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. Steamboats sometimes use the prefix designation SS, S.S. or S/S or PS, however these designations are most often used for steamships.

River Cray river in the United Kingdom

The River Cray is the largest tributary of the Darent. It is the prime river of outer, south-east Greater London, rising in Priory Gardens, Orpington, where rainwater percolates through chalk bedrock of the Downs to forms a pond where the eroded ground elevation gives way to impermeable clay. Initially it flows true to form northwards, past industrial and residential St Mary Cray, through St Paul's Cray and through Foots Cray, where it enters the parkland Foots Cray Meadows, flowing under by Five Arches bridge. It then flows by restored Loring Hall (c.1760), home of the Lord Castlereagh who took his own life there in 1822. It continues through North Cray and Bexley. It neighbours a restored Gothic (architecture) cold plunge bath house, built around 1766 as part of Vale Mascal Estate. It is then joined by the River Shuttle and then continues through the parkland of Hall Place, which was built for John Champneys in 1540. The Cray turns eastward through Crayford and Barnes Cray to join the Darent in Dartford Creek. The Creek is a well-watered partly tidal inlet between Crayford Marshes and Dartford Marshes by a slight projection of land, Crayford Ness. The villages through which the Cray flows are collectively known as "The Crays".

River Darent river in the United Kingdom

The Darent is a Kentish tributary of the River Thames and takes the waters of the River Cray as a tributary in the tidal portion of the Darent near Crayford, as illustrated by the adjacent photograph, snapped at high tide. 'Darenth' is frequently found in the spelling of the river's name in older books and maps, Bartholomew's "Canal's and River of England" being one example. Bartholomew's Gazetteer (1954) demonstrates that Darent means "clear water" and separately explains the other name. Considering the River Darent runs on a bed of chalk and its springs rise through chalk, this is not surprising. The original purity of the water was a major reason for the development of paper and pharmaceuticals in the area.

Antipater of Thessalonica was the author of over a hundred epigrams in the Greek Anthology. He is the most copious and perhaps the most interesting of the Augustan epigrammatists. He lived under the patronage of Lucius Calpurnius Piso, who appointed him governor of Thessalonica.

The Hunter Wheel was a device intended to improve the propulsion of steam-powered ships and evaluated in the middle 1840s. At the time, as ships were transitioning from sail to steam engine power, the understanding of the principles of hydrodynamics and efficient use of steam was in its infancy.

River Bewl river in the United Kingdom

The River Bewl is a tributary of the River Teise in Kent, England. Its headwaters are in the High Weald, in Sussex between Lamberhurst, Wadhurst and Flimwell. The valley is deeply incised into Tunbridge Wells red sandstone, with a base of alluvium on Wadhurst clay.

Sakia

A sakia, alternative spelling sakieh or saqiya, also called Persian wheel, tablia, and in Latin tympanum is a mechanical water lifting device, similar in function to a scoop wheel, which uses buckets, jars, or scoops fastened either directly to a vertical wheel, or to an endless belt activated by such a wheel. The vertical wheel is itself attached by a drive shaft to a horizontal wheel, which is traditionally set in motion by animal power Because it is not using the power of flowing water, the sakia is different from a noria and any other type of water-wheel. It is still used in India, Egypt and other parts of the Middle East, and in the Iberian Peninsula and the Balearic Islands. It may have been invented in Hellenistic Egypt, Persia or India. The sakia was mainly used for irrigation, but not exclusively, as the example of Qusayr Amra shows, where it was used at least in part to provide water for a royal bathhouse.

Roller ship

The roller ship was an unconventional and unsuccessful ship design of the late nineteenth century, which attempted to propel itself by means of large wheels. Only one such vessel was constructed—Ernest Bazin, named for its inventor—which was found to be impractical.

Ship mill type of watermill

A ship mill is a type of watermill. The milling and grinding technology and the drive (waterwheel) are built on a floating platform on this type of mill. Its first recorded use dates back to mid-6th century AD Italy.

<i>Stadt Zürich</i> (ship, 1909) steam paddle ship on Lake Zurich in Switzerland

The PS Stadt Zürich is the older of the two remaining steam paddle ships on Lake Zürich. Stadt Zürich was built in 1909 by Escher, Wyss & Cie. in Zürich for the Zürichsee-Schifffahrtsgesellschaft, as the 32nd tourist ship on Lake Zürich. In contrast to most other Swiss paddle steamers, the most striking features of this vessel and its sister ship Stadt Rapperswil (1914) are a short smoke stack, and a spacious 1st class upper deck.

Paddle wheel part of a boat

A paddle wheel is a form of waterwheel or impeller in which a number of paddles are set around the periphery of the wheel. It has several uses, some of which are:

Benoît Fourneyron was a French engineer, born in Saint-Étienne, Loire. Fourneyron made significant contributions to the development of water turbines.

Gristmill mill; grinds grain into flour

A gristmill grinds cereal grain into flour and middlings. The term can refer to both the grinding mechanism and the building that holds it.

Steam-powered vessels

Steam-powered vessels include steamboats and steamships. Smaller steamboats were developed first. They were replaced by larger steamships which were often ocean-going. Steamships required a change in propulsion technology from sail to paddlewheel to screw to steam turbines. The latter innovation changed the design of vessels to one that could move faster through the water. Engine propulsion changed to steam turbine in the early 20th century. In the latter part of the 20th century, these, in turn, were replaced by gas turbines.
