  2. 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.

  3. Low-head hydro power - Wikipedia

    en.wikipedia.org/wiki/Low-head_hydro_power

    Kaplan turbine: This turbine is a propeller-type turbine which has adjustable blades to achieve efficiency over a wide range of heads and flows. The Kaplan can be used at low to medium heads (1.5–20 metres) and medium to high flows (3 m 3 /s–30 m 3 /s). For higher flows multiple turbines can be used.

  4. Water turbine - Wikipedia

    en.wikipedia.org/wiki/Water_turbine

    Kaplan turbine and electrical generator cut-away view. 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 ...

  5. Evolution from Francis turbine to Kaplan turbine - Wikipedia

    en.wikipedia.org/wiki/Evolution_from_Francis...

    Turbines are sometimes differentiated on the basis of the type of inlet flow, whether the inlet velocity is in axial direction, radial direction or a combination of both. . The Francis turbine is a mixed hydraulic turbine (the inlet velocity has Radial and tangential components) while the Kaplan turbine is an axial hydraulic turbine (the inlet velocity has only axial velocity componen

  6. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    The turbine flowmeter (better described as an axial turbine) translates the mechanical action of the turbine rotating in the liquid flow around an axis into a user-readable rate of flow (gpm, lpm, etc.). The turbine tends to have all the flow traveling around it. The turbine wheel is set in the path of a fluid stream.

  7. Tidal barrage - Wikipedia

    en.wikipedia.org/wiki/Tidal_barrage

    ρ is the density of water = 1025 kg per cubic meter (seawater varies between 1021 and 1030 kg per cubic meter) and; g is the acceleration due to the Earth's gravity = 9.81 meters per second squared. The factor half is due to the fact, that as the basin flows empty through the turbines, the hydraulic head over the dam reduces. The maximum head ...

  8. Vargfors Hydroelectric Power Station - Wikipedia

    en.wikipedia.org/wiki/Vargfors_Hydroelectric...

    The power plant contains 1 Francis-and 1 Kaplan turbine-generator. The total nameplate capacity is 122 MW. Its average annual generation is 452 GWh. The hydraulic head is 49 m. [1] Maximum flow is 136 m³/s. [2]

  9. Almatti Dam - Wikipedia

    en.wikipedia.org/wiki/Almatti_Dam

    The facility uses vertical Kaplan turbines: five 55MW generators and one 15MW generator. Water is released in to the Narayanpur reservoir after using for power generation to serve the downstream irrigation needs. Two separate facilities namely, Almatti 1 Powerhouse and Almatti II Powerhouse each separated by distance do provide power generation ...
