high-head turbine
1turbine — /terr bin, buyn/, n. any of various machines having a rotor, usually with vanes or blades, driven by the pressure, momentum, or reactive thrust of a moving fluid, as steam, water, hot gases, or air, either occurring in the form of free jets or as …
2Turbine — A turbine is a rotary engine that extracts energy from a fluid flow. Claude Burdin (1788 1873) coined the term from the Latin turbo , or vortex, during an 1828 engineering competition. Benoit Fourneyron (1802 1867), a student of Claude Burdin,… …
3Head-mounted display — A head mounted display or helmet mounted display, both abbreviated HMD, is a display device, worn on the head or as part of a helmet, that has a small display optic in front of one (monocular HMD) or each eye (binocular HMD). A binocular head… …
4Head transplant — A head transplant is a surgical operation involving the grafting of an organism s head onto the body of another. It should not be confused with another, hypothetical, surgical operation, the brain transplant. Head transplantation involves… …
5High-temperature superconductivity — Unsolved problems in physics What causes superconductivity at temperatures above 50 kelvin? High temperature superconductors (abbreviated high Tc or HTS) are materials that have a superconducting transition temperature (Tc) above 30 K… …
6Water turbine — A water turbine is a rotary engine that takes energy from moving water.Water turbines were developed in the nineteenth century and were widely used for industrial power prior to electrical grids. Now they are mostly used for electric power… …
7Hydrostatic head — When generating hydropower, the head is a general term used to describe the distance that a given water source has to fall before the point where power is generated. Ultimately the force responsible for hydropower is gravity, so a… …
8Pelton Turbine — A type of impulse hydropower turbine where water passes through nozzles and strikes cups arranged on the periphery of a runner, or wheel, which causes the runner to rotate, producing mechanical energy. The runner is fixed on a shaft, and the… …
9Kaplan turbine — The Kaplan turbine is a propeller type water turbine that has adjustable blades. It was developed in 1913 by the Austrian professor Viktor Kaplan. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power… …
10Cross-flow turbine — Cross flow turbine. Image credit; European Communities, Layman s Guidebook (on how to develop a small hydroelectric site) A cross flow turbine, Banki Michell turbine, or Ossberger turbine[1] is a water turbine developed by the Australian Anthony… …
