  2. Water hammer - Wikipedia

    en.wikipedia.org/wiki/Water_hammer

    Hydraulic shock (colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly: a momentum change. It is usually observed in a liquid but gases can also be affected.

    Water hammer: Water hammer (or more generally, fluid hammer) is a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). Water hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave ...

  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 ...

    Water hammer, a pressure surge caused by a fluid suddenly changing velocity Hydrostatic shock , a hypothesized phenomenon by which pressure waves from a high-speed projectile entering a victim cause injury away from an entry wound

  8. Expansion tank - Wikipedia

    en.wikipedia.org/wiki/Expansion_tank

    An expansion tank or expansion vessel is a small tank used to protect closed water heating systems and domestic hot water systems from excessive pressure. The tank is partially filled with air, whose compressibility cushions shock caused by water hammer [citation needed] and absorbs excess water pressure caused by thermal expansion. [1]
