Hanabanilla Dam
The Hanabanilla Dam is an embankment dam on the Hanabanilla River near the village of El Salto del Hanabanilla in Villa Clara Province, Cuba. The purpose of the dam is to provide water for irrigation and municipal uses and to generate hydroelectric power. Overview The dam withholds a reservoir of and the power station, located near its base, has an installed capacity of 43 MW. It is the largest hydroelectric power station in the country. Near the southern end of the reservoir is Jibacoa Dam, an auxiliary dam, which closes off one valley to create the existing large reservoir. The dam was constructed between 1958 and 1961. The power station was commissioned in 1963. In March 2014 a rehabilitation of the power station began.

Villa Clara Province
Villa Clara is one of the provinces of Cuba. It is located in the central region of the island bordering with the Atlantic at north, Matanzas Province by west, Sancti Spiritus Province by east, and Cienfuegos Province on the South. Villa Clara shares with Cienfuegos and Sancti Spiritus on the south the Escambray Mountain Range. Its main cities are Santa Clara (the capital), Remedios, Sagua La Grande, Camajuani, Caibarién, Ranchuelo, Placetas, and Manicaragua. History Prior to 1976, the current provinces of Cienfuegos, Sancti Spíritus, and Villa Clara were all part of the now obsolete province of Las Villas, but Villa Clara is still referred some times just as "Las Villas" using the shorter old name. Santa Clara was the capital of historical Las Villas and still capital of Villa Clara province. That old name itself, Spanish for "The Cities", refers to the four original 16th and 17th-century cities founded in this vast territory: San Juan de los Remedios, Sancti Spíri ...

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Francis-type
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for diff ...

Embankment Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuba
Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos. Cuba is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both the American state of Florida and the Bahamas, west of Hispaniola ( Haiti/Dominican Republic), and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The official area of the Republic of Cuba is (without the territorial waters) but a total of 350,730 km² (135,418 sq mi) including the exclusive economic zone. Cuba is the second-most populous country in the Caribbean after Haiti, with over 11 million inhabitants. The territory that is now Cuba was inhabited by the Ciboney people from the 4th millennium BC with the Gua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Escambray Mountains
The Escambray Mountains () are a mountain range in the central region of Cuba, in the provinces of Sancti Spíritus, Cienfuegos and Villa Clara. Overview The Escambray Mountains are located in the south-central region of the island, extending about from east to west, and from north to south. Their highest peak, Pico San Juan, rises to above sea level. The Escambray range is divided into two sections by the Agabama River. The western part is called the Guamuhaya Mountains, and the eastern part, raising between Trinidad and Sancti Spiritus, is best known as Sierra de Sancti Spíritus. After Pico San Juan, the highest points are Caballete de Casas, Gavilanes, Loma de Banao, Caja de Agua, and Pico Tuerto. Topes de Collantes is a nature reserve park established in the south-eastern ranges of Escambray Mountains, protecting and showcasing caves, rivers, waterfalls, and canyons.

Dams In Cuba
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
