  2. Euler's pump and turbine equation - Wikipedia

    en.wikipedia.org/wiki/Euler's_pump_and_turbine...

    The color triangles formed by velocity vectors u,c and w are called velocity triangles and are helpful in explaining how pumps work.. and are the absolute velocities of the fluid at the inlet and outlet respectively.

  3. Hydropower - Wikipedia

    en.wikipedia.org/wiki/Hydropower

    Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, 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 ...

  4. Hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Hydroelectricity

    Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, [1] which is more than all other renewable sources combined and also more than nuclear power. [2] Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. [2]

  5. Chilton and Colburn J-factor analogy - Wikipedia

    en.wikipedia.org/wiki/Chilton_and_Colburn_J...

    This equation permits the prediction of an unknown transfer coefficient when one of the other coefficients is known. The analogy is valid for fully developed turbulent flow in conduits with Re > 10000, 0.7 < Pr < 160, and tubes where L/d > 60 (the same constraints as the Sieder–Tate correlation). The wider range of data can be correlated by ...

  6. Conduit hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Conduit_hydroelectricity

    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 ]

  7. Hydraulic power - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_power

    Hydropower, power derived from the energy of falling or fast running water; Fluid power, use of fluids under pressure to generate, control, and transmit power; Power supplied via a Hydraulic power network, using pressurised water. Erosive work done by hydraulic action of the sea or other water source.

  8. Lester Allan Pelton - Wikipedia

    en.wikipedia.org/wiki/Lester_Allan_Pelton

    Pelton patented his wheel as well as his novel design of the double cup runner, and in 1888 formed the Pelton Water Wheel Company in San Francisco to supply the growing demand for hydropower and hydroelectricity throughout the West and world-wide. [6] 'Pelton' is a trademark name for the products of that company, but the term is widely used ...

  9. Magnetohydrodynamic generator - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_generator

    A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity.An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.
