2. Drainage equation - Wikipedia

   en.wikipedia.org/wiki/Drainage_equation

   the discharge rate (Q) from the recharge rate (R) in a water balance as detailed in the article: hydrology (agriculture) 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)

3. Low-flow fixtures - Wikipedia

   en.wikipedia.org/wiki/Low-flow_fixtures

   Kitchen and bathroom faucets were limited to a flow rate of 2.2 gpm (gallons per minute) at 60 psi, and residential shower heads were limited to a flowrate of 2.5 gpm at 80 psi. [ 3 ] In response to an increasing number of water shortages and increased water utility rates there has been recent legislation by many states leading the way in water ...

4. Flow in partially full conduits - Wikipedia

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

   In practice, it is common to restrict the flow below the value of 0.82D to avoid the region of two normal depths due to the fact that if the depth exceeds the depth of 0.82D then any small disturbance in water surface may lead the water surface to seek alternate normal depths thus leading to surface instability.

5. Plumbing fixture - Wikipedia

   en.wikipedia.org/wiki/Plumbing_fixture

   The most common plumbing fixtures are: Bathtubs; Bidets; Channel drains; Drinking fountains; Showers; Sinks; Tap (connections for water hoses) . Tapware - an industry term for that sub-category of plumbing fixtures consisting of tap valves, also called water taps (British English) or faucets (American English), and their accessories, such as water spouts and shower heads.

6. Volumetric flow rate - Wikipedia

   en.wikipedia.org/wiki/Volumetric_flow_rate

   In hydrometry, the volumetric flow rate is known as discharge. Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol q, with units of m 3 /(m 2 ·s), that is, m·s −1. The integration of a flux over an area gives the volumetric flow rate. The SI unit is cubic metres per ...

7. Sink - Wikipedia

   en.wikipedia.org/wiki/Sink

   Some public restrooms feature automatic faucets, which use a motion-sensing valve to detect the user's hands moving beneath the tap and turn the water on. Some kitchen sinks also come equipped with a sink sprayer. Sinks, especially those made of stainless steel, can be fitted with an integrated drainboard, allowing for the draining of washed ...

8. 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.

9. Discharge (hydrology) - Wikipedia

   en.wikipedia.org/wiki/Discharge_(hydrology)

   A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure.
