2. Plumbing fixture - Wikipedia

   en.wikipedia.org/wiki/Plumbing_fixture

   Each of these plumbing fixtures has one or more water outlets and a drain. In some cases, the drain has a device that can be manipulated to block the drain to fill the basin of the fixture. Each fixture also has a flood rim, or level at which water will begin to overflow. Most fixtures also have an overflow, which is a conduit for water to ...

3. Faucet aerator - Wikipedia

   en.wikipedia.org/wiki/Faucet_aerator

   When an aerator is added to the faucet (or fluid stream), there is a region of high pressure created behind the aerator. Because of the higher pressure behind the aerator and the low pressure in front of it (outside the faucet), due to Bernoulli's principle there is an increase in velocity of the fluid flow.

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. Mechanical, electrical, and plumbing - Wikipedia

   en.wikipedia.org/wiki/Mechanical,_electrical...

   MEP specifically encompasses the in-depth design and selection of these systems, as opposed to a tradesperson simply installing equipment. For example, a plumber may select and install a commercial hot water system based on common practice and regulatory codes. A team of MEP engineers will research the best design according to the principles of ...

6. Flow in partially full conduits - Wikipedia

   en.wikipedia.org/wiki/Flow_in_partially_full...

   The variations of Q/Q (full) and V/V (full) with H/D ratio is shown in figure(b).From the equation 5, maximum value of Q/Q (full) is found to be equal to 1.08 at H/D =0.94 which implies that maximum rate of discharge through a conduit is observed for a conduit partly full.

7. Tap (valve) - Wikipedia

   en.wikipedia.org/wiki/Tap_(valve)

   Faucet is the most common term in the US, similar in use to "tap" in British English, e.g. "water faucet" (although the term "tap" is also used in the US). Spigot is used by professionals in the trade (such as plumbers), and typically refers to an outdoor fixture.

8. Torricelli's law - Wikipedia

   en.wikipedia.org/wiki/Torricelli's_law

   For low viscosity liquids (such as water) flowing out of a round hole in a tank, the discharge coefficient is in the order of 0.65. [4] By discharging through a round tube or hose, the coefficient of discharge can be increased to over 0.9. For rectangular openings, the discharge coefficient can be up to 0.67, depending on the height-width ratio.

9. CEE 7 standard AC plugs and sockets - Wikipedia

   en.wikipedia.org/wiki/CEE_7_standard_AC_plugs...

   The CEE 7/5 socket and CEE 7/6 plug are defined in French standard NF C 61-314 "Plugs and socket-outlets for household and similar purposes" (which also includes CEE 7/7, 7/16 and 7/17 plugs) The socket has a predominantly circular recess which is 15 mm (0.591 in) deep with two symmetrical round apertures and a round 4.8 mm (0.189 in) earth pin ...
