As shown in this drawing, the hydrostatic head is the vertical distance between the water level in the reservoir and the turbine that is turned by the flowing water. When generating hydropower, the head is the distance that a given water source has to fall before the point where power is generated. Ultimately the force responsible for ...
Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy production.
An ad for various styles of straw hats. A straw cone hat worn by a Japanese buddhist monk. A straw hat is a wide-brimmed hat woven out of straw or straw-like synthetic materials. [1] Straw hats are a type of sun hat designed to shade the head and face from direct sunlight, but are also used in fashion as a decorative element or a uniform.
Conduit hydroelectricity (or conduit hydropower) is a method of using mechanical energy of water as part of the water delivery system through man-made conduits to generate electricity. Generally, the conduits are existing water pipelines such as in public water supply. [1] Some definitions expand the definition of conduits to be existing ...
Low-head hydro power refers to the development of hydroelectric power where the head is typically less than 20 metres, although precise definitions vary. [1] Head is the vertical height measured between the hydro intake water level and the water level at the point of discharge. Using only a low head drop in a river or tidal flows to create ...
Lester Allan Pelton (September 5, 1829 – March 14, 1908) was an American inventor who contributed significantly to the development of hydroelectricity and hydropower in the American Old West as well as world-wide. In the late 1870s, he invented the Pelton water wheel, at that time the most efficient design of the impulse water turbine.
Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. [1] Exact definitions vary, but a "small hydro" project is less than 50 megawatts (MW), and can be further subdivide by scale into "mini" (<1MW), "micro" (<100 kW ...
The 220kV transmission line of the Upper Kotmale Hydro-power Project connects the power station located at Niyamgamdora, Kotmale, to the national grid via Kotmale switch yard located in Atabage, Gampola. The line consists of 45 towers and has a length of 15.5 km. The double circuit transmission line has a capacity of 220 MW per circuit.
