    en.wikipedia.org/wiki/Bathtub_curve

    The bathtub curve is a particular shape of a failure rate graph. This graph is used in reliability engineering and deterioration modeling. The 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions: The first region has a decreasing failure rate due to early failures.

  3. Torricelli's law - Wikipedia

    en.wikipedia.org/wiki/Torricelli's_law

    By measuring the level of water remaining in the vessel, the time can be measured with uniform graduation. This is an example of outflow clepsydra. Since the water outflow rate is higher when the water level is higher (due to more pressure), the fluid's volume should be more than a simple cylinder when the water level is high.

    Pool drain vortex as viewed from above the water at Grange Park wading pool Underwater view of drain, showing vortex-formation phenomenon. A drain is the primary vessel or conduit for unwanted water or waste liquids to flow away, either to a more useful area, funnelled into a receptacle, or run into sewers or stormwater mains as waste discharge to be released or processed.

  5. Interstitial condensation - Wikipedia

    en.wikipedia.org/wiki/Interstitial_condensation

    Interstitial condensation is a type of condensation that may occur within an enclosed wall, roof or floor cavity structure, which can create dampening. When moisture-laden air at dew point temperature penetrates inside a cavity of the structure, it condenses into liquid water on that surface. The moisture laden air can penetrate into hidden ...

  6. The Bathtub - Wikipedia

    en.wikipedia.org/wiki/The_Bathtub

    Manually removing water from this area would have severely altered the water levels surrounding the World Trade Center site and thus would have jeopardized the foundations of nearby buildings, causing them to sink. This is why the Bathtub method was used. [2] The "Bathtub" at the National September 11 Memorial & Museum

  7. Water damage - Wikipedia

    en.wikipedia.org/wiki/Water_damage

    Water damage restoration is often prefaced by a loss assessment and evaluation of affected materials. The damaged area is inspected with water sensing equipment such as probes and other infrared tools in order to determine the source of the damage and possible extent of areas affected. Emergency mitigation services are the first order of business.

  9. Air gap (plumbing) - Wikipedia

    en.wikipedia.org/wiki/Air_gap_(plumbing)

    In the base cabinet under the sink, the drain hose from the dishwasher feeds the "top" of the air gap, and the "bottom" of the air gap is plumbed into the sink drain below the basket, or into a garbage disposal unit. When installed and maintained properly, the air gap works as described above, and prevents drain water from the sink from backing ...
