  3. Water turbine - Wikipedia

    en.wikipedia.org/wiki/Water_turbine

    The runner of the small water turbine. A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation.

  4. Francis turbine - Wikipedia

    en.wikipedia.org/wiki/Francis_turbine

    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. [1] The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. [1]

  5. Pelton wheel - Wikipedia

    en.wikipedia.org/wiki/Pelton_wheel

    A wheel power divided by the initial jet power, is the turbine efficiency, η = 4u(V i − u)/V i 2. It is zero for u = 0 and for u = V i . As the equations indicate, when a real Pelton wheel is working close to maximum efficiency, the fluid flows off the wheel with very little residual velocity. [ 11 ]

    en.wikipedia.org/wiki/Pico_hydro

    A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes. [2]

  8. Water power engine - Wikipedia

    en.wikipedia.org/wiki/Water_power_engine

    The water powered turbines used in these dams need little maintenance, are easily upgradable with modern technology, and have a lifespan of 50–100 years. Clean energy created by hydro power plants attracts positive results in otherwise remote areas. It enhances commerce and gives rise to more industry.

  9. Kaplan turbine - Wikipedia

    en.wikipedia.org/wiki/Kaplan_turbine

    A Bonneville Dam Kaplan turbine after 61 years of service. The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, [1] who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level.
