York Haven Dam
The York Haven Dam is a low head, run-of-the river, dam and hydroelectric plant that is located on the Susquehanna River in the United States. This dam is situated south of Harrisburg, Pennsylvania, at the Conewago Falls impounding about of the river to the west side of Three Mile Island, where the river drops in . When the dam was completed in 1904, it was the third largest in the world. History and notable features The major axis of the diversion dam is north to south and connects to a headrace which heads southeast. The dam and headrace are laid out along natural rock formations in the river. The south eastern end is situated on the "western" bank at York Haven. The north end lands at Three Mile Island. There is a smaller dam and fish passage further up the east side of Three Mile Island that completes the crossing to the eastern bank of the river. The hydroelectric plant is located at the south eastern end, near the western bank of the river. Segments of the dam are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kaplan Turbine
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm (Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brünn, Austria-Hungary (now Brno, Czechia), obtained his first patent for an adjustable blade propeller turbine in 1912. But t ...

Buildings And Structures In York County, Pennsylvania
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydroelectric Power Plants In Pennsylvania
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.

Dams In Pennsylvania
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] |
Energy Infrastructure Completed In 1904
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Dams And Reservoirs Of The Susquehanna River
The Susquehanna River, in the Mid-Atlantic States of the United States, has a collection of dams. These dams are used for power generation, flood control, navigation and recreation. These dams have local and regional environmental impacts on the river and the Chesapeake Bay, both positive and negative. Environmental impacts :''And by making it more Susquehanna specific.'' The dams have a positive impact on the environment. They slow water, trapping silt and pollutants. Conowingo Dam is credited with preventing much of the silt from Pennsylvania from reaching the Chesapeake Bay. The dam spillways can add oxygen to the water. The down stream side of dams is favored by aquatic birds, possibly because the fish that pass through the dam are a bit stunned. Conowingo Dam is noted for its bald eagles. Hydroelectric power is considered an environmentally friendly method of power generation. The dams also make a negative impact on the environment. They raise the water leve ...
