  3. Dry measure - Wikipedia

    en.wikipedia.org/wiki/Dry_measure

    In US customary units, most units of volume exist both in a dry and a liquid version, with the same name, but different values: the dry hogshead, dry barrel, dry gallon, dry quart, dry pint, etc. The bushel and the peck are only used for dry goods. Imperial units of volume are the same for both dry and liquid goods. They have a different value ...

    en.wikipedia.org/wiki/Dry_gallon

    The dry gallon's implicit value in the US system was originally one eighth of the Winchester bushel, which was a cylindrical measure of 18.5 inches (469.9 mm) in diameter and 8 inches (203.2 mm) in depth, making it an irrational number of cubic inches; its value to seven significant digits was 268.8025 cubic inches (4.404884 litres), from an ...

    An 80 US gal (300 L; 67 imp gal) electric storage tank water heater was able to have a minimum energy factor of 86% under the pre-2015 standard, while under the 2015 standard, the minimum energy factor for an 80-gallon electric storage tank water heater is now 197%, which is only possible with heat pump technology. This rating measures ...

  8. Sump pump - Wikipedia

    en.wikipedia.org/wiki/Sump_pump

    Sump pumps are used where basement flooding may otherwise happen, and to solve dampness where the water table is near or above the foundation of a structure. Sump pumps send water away from a location to any place where it is no longer problematic, such as a municipal storm drain, a dry well, or simply an open-air site downhill from the building (sometimes called "pumping to daylight").

  9. Pump-jet - Wikipedia

    en.wikipedia.org/wiki/Pump-jet

    A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump ...
