  2. Specific pump power - Wikipedia

    en.wikipedia.org/wiki/Specific_pump_power

    Specific Pump Power (SPP) is a metric in fluid dynamics that quantifies the energy-efficiency of pump systems. It is a measure of the electric power that is needed to operate a pump (or collection of pumps), relative to the volume flow rate. It is not constant for a given pump, but changes with both flow rate and pump pressure.

  3. Pumping station - Wikipedia

    en.wikipedia.org/wiki/Pumping_station

    The development of a packaged pump station system combined all components into a single housing which not only eliminates uneven settling issues, but pre-plumbing and outfitting each unit prior to installation can reduce the cost and time involved with civil work and site labor.

  4. Pumped-storage hydroelectricity - Wikipedia

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

    Electricity is created when water is let in via a reversible turbine integrated into the sphere. During off-peak hours, the turbine changes direction and pumps the water out again, using "surplus" electricity from the grid. The quantity of power created when water is let in, grows proportionally to the height of the column of water above the ...

  5. Pump - Wikipedia

    en.wikipedia.org/wiki/Pump

    Pump efficiency is defined as the ratio of the power imparted on the fluid by the pump in relation to the power supplied to drive the pump. Its value is not fixed for a given pump, efficiency is a function of the discharge and therefore also operating head.

  6. 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 ...

  7. Coefficient of performance - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_performance

    The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP is used in thermodynamics.

    Home values in the U.S. increased by about $2 trillion in 2023, reaching a whopping total value of $47.5 trillion. For home sellers, that’s good news. However, you shouldn’t assume that the ...

  9. Hand pump - Wikipedia

    en.wikipedia.org/wiki/Hand_pump

    A chain pump is a type of water pump that uses a chain to move water from one place to another. It works on the principle of a continuous loop of chain moving through a series of sprockets, with attached buckets that lift water as the chain passes over the top sprocket and discharge it as the chain reaches the bottom.
