  2. Solar-powered pump - Wikipedia

    en.wikipedia.org/wiki/Solar-powered_pump

    A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.

  3. Hydraulic ram - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_ram

    The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination ...

  4. Water pumping - Wikipedia

    en.wikipedia.org/wiki/Water_pumping

    Due to the rotation, water is then picked up by the tube and pumped upwards in the hose. The coil pump, as many low lift pumps, is commonly used for irrigation purposes and for drainage of lands. It is currently still used by farmers in Asia. [1] The coil pump was built as an alternative to the Archimedean screw. Unlike the Archimedean screw ...

    en.wikipedia.org/wiki/Adobe_Photoshop

    Adobe Photoshop is a raster graphics editor developed and published by Adobe for Windows and macOS.It was created in 1987 by Thomas and John Knoll.It is the most used tool for professional digital art, especially in raster graphics editing, and its name has become genericised as a verb (e.g. "to photoshop an image", "photoshopping", and "photoshop contest") [7] although Adobe disapproves of ...

  6. 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. Purulia Pumped Storage Power Station - Wikipedia

    en.wikipedia.org/wiki/Purulia_Pumped_Storage...

    The objective of project is to meet load demand by producing power through the turbines at the peak load time and utilize surplus power available of the system during off peak time by pumping the water to upper reservoir, thus achieving the flatter load demand curve and maintaining the frequency.

  8. Pump - Wikipedia

    en.wikipedia.org/wiki/Pump

    A small, electrically powered pump A large, electrically driven pump for waterworks near the Hengsteysee, Germany. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, [1] by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy.

  9. Osmotic power - Wikipedia

    en.wikipedia.org/wiki/Osmotic_power

    A 2012 study on efficiency from Yale University concluded that the highest extractable work in constant-pressure PRO with a seawater draw solution and river water feed solution is 0.75 kWh/m 3 (2.7 kJ/L) while the free energy of mixing is 0.81 kWh/m 3 (2.9 kJ/L) — a thermodynamic extraction efficiency of 91.0%.
