2. Drainage equation - Wikipedia

   en.wikipedia.org/wiki/Drainage_equation

   the permissible long term average depth of the water table (Dw) on the basis of agricultural drainage criteria; the soil's hydraulic conductivity (Ka and Kb) by measurements; the depth of the bottom of the aquifer (Di) the design drain spacing (L) can be found from the equation in dependence of the drain depth (Dd) and drain radius (r ...

3. Low-flow fixtures - Wikipedia

   en.wikipedia.org/wiki/Low-flow_fixtures

   Faucets that meet energy efficiency standards for WaterSense mustn’t use more than 1.5 gpm, a 32% decrease in flow rate over the federal requirement. [10] Reduced flow faucets often make use of flow restrictors or faucet aerators to reduce the flowrate of the water. Using a faucet with an aerator results in an average 42% reduction in water ...

4. Drain-waste-vent system - Wikipedia

   en.wikipedia.org/wiki/Drain-waste-vent_system

   A drain-waste-vent system (or DWV) is the combination of pipes and plumbing fittings that captures sewage and greywater within a structure and routes it toward a water treatment system.

5. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   These compression connections on water shutoff valves under a kitchen sink show evidence of slow seepage (greenish deposits). Valves stop (or regulate) the flow of liquids or gases. They are categorized by application, such as isolation, throttling, and non-return.

6. Watertable control - Wikipedia

   en.wikipedia.org/wiki/Watertable_control

   In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...

7. Torricelli's law - Wikipedia

   en.wikipedia.org/wiki/Torricelli's_law

   The depth at which two jets cross is the sum of their source depths. Every jet (even if not leaving horizontally) takes a parabolic path whose directrix is the surface of the water. Torricelli's law, also known as Torricelli's theorem, is a theorem in fluid dynamics relating the speed of fluid flowing from a hole to the height of fluid above ...

   depth: "distance of a point from a chosen reference surface measured downward along a line perpendicular to that surface." [1] height: "distance of a point from a chosen reference surface measured upward along a line perpendicular to that surface"; [1] ISO 6709 (2008 version) makes the following additional definition:

9. CEE 7 standard AC plugs and sockets - Wikipedia
