A smooth and rounded outlet has c=0.9, a square and sharp outlet has c=0.8, and a square outlet which projects into the barrel has c=0.7. d = diameter of the outlet (inches) p = stagnation pressure or pitot pressure (velocity head) (pounds per square inch)
A Fixture Unit is not a flow rate unit but a design factor. A fixture unit is equal to 1 cubic foot (0.028 m 3) of water drained in a 1 + 1 ⁄ 4 inches (32 mm) diameter pipe over one minute. [2] One cubic foot of water is roughly 7.48 US gallons (28.3 L; 6.23 imp gal). A Fixture Unit is used in plumbing design for both water supply and waste ...
The miner's inch is a method of measuring the amount of flow a particular water supply system (such as a flume or sluice) is capable of supplying. The miner ’s inch measures the amount of water that would flow through a slot of a given area at a given pressure (for example, at a head of 6 inches of water , or 1.5 kPa .)
The integration of a flux over an area gives the volumetric flow rate. The SI unit is cubic metres per second (m 3 /s). Another unit used is standard cubic centimetres per minute (SCCM). In US customary units and imperial units, volumetric flow rate is often expressed as cubic feet per second (ft 3 /s) or gallons per minute (either US or ...
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms ...
The plant has a treatment capacity of 384 million gallons per day (mgd) or 1.45 billion liters per day, with a peak capacity (partial treatment during large storms) of over 1 billion gallons per day (3.8 billion liters/day). The plant occupies 153 acres (0.62 km 2) in the southwest quadrant of Washington, D.C., and discharges to the Potomac River.

The water system has a storage capacity of 550 billion US gal (2.1 billion m 3) and provides over 1.2 billion US gal (4.5 million m 3) per day of drinking water to more than eight million city residents, and another one million users in four upstate counties bordering on the system.
