  2. Layered charge storage - Wikipedia

    en.wikipedia.org/wiki/Layered_charge_storage

    Layered or stratified charge storage is hot water storage tank, typically for solar thermal energy. The warmest storage layer is the top storage cylinder and below this there are colder storage layers through natural layering. The water is fed into different storage levels, depending on the available feed temperature and current temperature ...

  4. Pressure tank - Wikipedia

    en.wikipedia.org/wiki/Pressure_tank

    The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring to the diagram on the right, a pressure tank is generally pressurized when empty with a "charging pressure" P c, which is usually about 2 psi below the turn-on pressure P lo (Case 1).

  5. Drainage equation - Wikipedia

    en.wikipedia.org/wiki/Drainage_equation

    The blue figure shows an example of results of a computer aided calculation with the amplified drainage equation using the EnDrain program. [11] It shows that incorporation of the incoming energy associated with the recharge leads to a somewhat deeper water table .

  6. Pressure vessel - Wikipedia

    en.wikipedia.org/wiki/Pressure_vessel

    The ASME definition of a pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. [2]The Australian and New Zealand standard "AS/NZS 1200:2000 Pressure equipment" defines a pressure vessel as a vessel subject to internal or external pressure, including connected components and accessories up to the connection to external ...

  7. Hydraulic calculation - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_calculation

    In locations where a municipal connection is not possible or practical, the required water may be drawn from an open body of water (e.g., lake, pond, river) or a water storage tank. Hydraulic calculations determine if the available water supply pressure is adequate to provide the sprinkler system design flowrate.

  8. Specific storage - Wikipedia

    en.wikipedia.org/wiki/Specific_storage

    The specific storage is the amount of water that a portion of an aquifer releases from storage, per unit mass or volume of the aquifer, per unit change in hydraulic head, while remaining fully saturated. Mass specific storage is the mass of water that an aquifer releases from storage, per mass of aquifer, per unit decline in hydraulic head:

  9. Flexible tank - Wikipedia

    en.wikipedia.org/wiki/Flexible_tank

    A portable flexible tank A 60,000-litre flexible tank A flexible tank mounted on a light truck to provide drinking water. Flexible tanks (also flexi-bags, flexibags and flexi-tanks) are a kind of storage equipment for liquids such as water or oil. Compared to steel tanks, flexible tanks have many advantages, including lighter weight and being ...
