Claverton Pumping Station
Claverton Pumping Station in the village of Claverton, Somerset, Claverton, in the English county of Somerset, pumps water from the River Avon, Bristol, River Avon to the Kennet and Avon Canal using power from the flow of the river. It is a Grade I listed building, having been upgraded from Grade II in 2019. The pumping station was built by John Rennie (engineer), John Rennie between 1809 and 1813 to overcome water supply problems on the canal. It uses a wide wooden Water wheel#Breastshot wheel, breastshot water wheel to drive two Boulton and Watt long cast iron rocking beams, which power lift pumps to raise water up to the canal. The pumping station has undergone several modifications since its initial construction, including revising the wheel into two sections each wide separated by a gap. The station's operational life ended in 1952, by which time its maintenance and repair had become uneconomical in the light of falling traffic on the canal. In the 1960s and 1970s rest ...

Pumping Station
Pumping stations, also called pumphouses in situations such as well drilling, drilled wells and drinking water, are facilities containing pumps and equipment for pumping fluids from one place to another. They are used for a variety of infrastructure systems, such as the supply of water to canals, the drainage of low-lying land, and the removal of sewage to processing sites. A pumping station is an integral part of a pumped-storage hydroelectricity installation. Canal water supply In countries with canal systems, pumping stations are also frequent. Because of the way the system of canal locks work, water is lost from the upper part of a canal each time a vessel passes through. Also, most lock gates are not watertight, so some water leaks from the higher levels of the canal to those lower down. Obviously, the water has to be replaced or eventually the upper levels of the canal would not hold enough water to be navigable. Canals are usually fed by diverting water from streams and ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |

Iroko
Iroko (also known as in Igbo language, '' in the Urhobo language of Southern Nigeria, and as odum in the Kwa languages of Ghana) is a large hardwood tree from the west coast of tropical Africa that can live up to 500 years. This is the common name for the genus ''Milicia'', in which there are two recognized species, which are closely related: ''Milicia excelsa'' and '' Milicia regia''. The genus name of ''Milicia'' is in honour of Milici (19th and 20th centuries), an administrator in Portuguese East Africa (in modern-day Mozambique) who supported the work of the author of the genus, Thomas Robertson Sim. It was first described and published in Forest Fl. Port. E. Afr. on page 97 in 1909. The tree is known to the Yoruba as , or and is believed to have healing properties. Iroko is known to the Igbo people as wood. It is one of the woods sometimes referred to as African teak, although it is unrelated to the teak family. The wood colour is initially yellow but darkens to a riche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sluice
Sluice ( ) is a word for a channel controlled at its head by a movable gate which is called a sluice gate. A sluice gate is traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway and can be considered as a bottom opening in a wall. Sluice gates are one of the most common hydraulic structures in controlling flow rate and water level in open channels such as rivers and canals. They also could be used to measure the flow. A water channel containing a sluice gate forms a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a River Sluice used in gold prospecting or fossicking. A mill race, leet, flume, penstock or lade is a sluice channeling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry. They are also used in wastewater treatment plants and to recover minerals in minin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leat
A leat (; also lete or leet, or millstream) is the name, common in the south and west of England and in Wales, for an artificial watercourse or aqueduct dug into the ground, especially one supplying water to a watermill or its mill pond. Other common uses for leats include delivery of water for hydraulic mining and mineral concentration, for irrigation, to serve a dye works or other industrial plant, and provision of drinking water to a farm or household or as a catchment cut-off to improve the yield of a reservoir. According to the ''Oxford English Dictionary'', ''leat'' is cognate with ''let'' in the sense of "allow to pass through". Other names for the same thing include ''fleam'' (probably a leat supplying water to a mill that did not have a millpool). In parts of northern England, for example around Sheffield, the equivalent word is ''goit''. In southern England, a leat used to supply water for water-meadow irrigation is often called a ''carrier'', ''top carrier'', or ' ...

Warleigh Weir
Warleigh Weir is a river structure at Warleigh on the River Avon, Bristol, River Avon in Somerset, England, upstream from the city of Bath, Somerset, Bath. The weir was originally built to supply a head of water to a gristmill, grist mill at Claverton, Somerset, Claverton. The weir was subsequently raised by a height of 12 inches between 1809 and 1813 as part of the construction program for the Claverton Pumping Station, which sits on the site of the old grist mill. The weir is accessed from the adjacent island which is created from the bifurcation of the river running to the Claverton Pumping station and the main flow of the River Avon. The weir and the bridge to the island are both owned by the Canal & River Trust. Recreation Warleigh Weir has been a popular local swimming spot for over 100 years. The river island—typically used to access the weir—is privately owned and is designated agricultural land. There is a public footpath across the field, to the old Ferry Steps, ...

Weatherboarding
Clapboard (), also called bevel siding, lap siding, and weatherboard, with regional variation in the definition of these terms, is wooden siding of a building in the form of horizontal boards, often overlapping. ''Clapboard'' in modern American usage is a word for long, thin boards used to cover walls and (formerly) roofs of buildings. Historically, it has also been called ''clawboard'' and ''cloboard''. In the United Kingdom, Australia and New Zealand, the term ''weatherboard'' is always used. An older meaning of "clapboard" is small split pieces of oak imported from Germany for use as barrel staves, and the name is a partial translation (from , "to fit") of Middle Dutch and related to German . Types Riven Clapboards were originally riven radially producing triangular or "feather-edged" sections, attached thin side up and overlapped thick over thin to shed water.

Hip Roof
A hip roof, hip-roof or hipped roof, is a type of roof where all sides slope downwards to the walls, usually with a fairly gentle slope (although a tented roof by definition is a hipped roof with steeply pitched slopes rising to a peak). Thus, a hipped roof has no gables or other vertical sides to the roof. A square hip roof is shaped like a pyramid. Hip roofs on houses may have two triangular sides and two trapezoidal ones. A hip roof on a rectangular plan has four faces. They are almost always at the same pitch or slope, which makes them symmetrical about the centerlines. Hip roofs often have a consistent level fascia, meaning that a gutter can be fitted all around. Hip roofs often have dormer slanted sides. Construction Hip roofs are more difficult to construct than a gabled roof, requiring more complex systems of rafters or trusses. Hip roofs can be constructed on a wide variety of plan shapes. Each ridge is central over the rectangle of the building below it. The t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slate
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates will display a property called fissility, forming smooth flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen, en masse, covering roofs. However, slate occurs in a variety of colors even from a single locality; for ex ...
