  2. Micro hydro - Wikipedia

    en.wikipedia.org/wiki/Micro_hydro

    The available power, in kilowatts, from such a system can be calculated by the equation P=Q*H/k, where Q is the flow rate in gallons per minute, H is the static head, and k is a constant of 5,310 gal*ft/min*kW. [7] For instance, for a system with a flow of 500 gallons per minute and a static head of 60 feet, the theoretical maximum power output ...

    The mostly used turbines are Pelton and Cross-flow types. Most of the MHP turbines are manufactured locally. The first turbine manufactured at the Balaju Yantra Shala Pvt. Ltd. (established 1960) was a 5 kW propeller turbine for the first MHP of Nepal in 1962. Kathmandu Metal Industries Pvt. Ltd., Nepal YantraShala Energy, Nepal Hydro & Electric Pvt. Ltd., Nepal Machine and Steel Structure, a

  4. Microgeneration - Wikipedia

    en.wikipedia.org/wiki/Microgeneration

    Microgeneration technologies include small-scale wind turbines, micro hydro, solar PV systems, microbial fuel cells, ground source heat pumps, and micro combined heat and power installations. [1] These technologies are often combined to form a hybrid power solution that can offer superior performance and lower cost than a system based on one ...

  5. Pumped-storage hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Pumped-storage...

    Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off ...

  7. Small hydro - Wikipedia

    en.wikipedia.org/wiki/Small_hydro

    Small power plant of Licq-Athérey (Pyrénées-Atlantiques, France). An 1895 hydroelectric plant near Telluride, Colorado.. 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]

  8. Low-head hydro power - Wikipedia

    en.wikipedia.org/wiki/Low-head_hydro_power

    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.

  9. List of unsolved problems in physics - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.
