A typical water meter register showing a meter reading of 8.3 gallons. Notice the black "1" on the odometer has not yet fully turned over, so only the red hand is read. Water meters connected to remote reading devices through three-wire cables. There are several types of registers on water meters.
American Water Works Association (AWWA) is an international non-profit, scientific and educational association founded to improve water quality and supply. Established in 1881, it is a lobbying organization representing a membership (as of 2024) of around 50,000 members worldwide.
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 ...
End uses of water for households in the U.S. in gallons per household per day and percent of indoor use [1]. Residential water use (also called domestic use, household use, or tap water use) includes all indoor and outdoor uses of drinking quality water at single-family and multifamily dwellings. [2]
The water equivalent is calculated for the following: Meter water equivalent , a standard measure of cosmic ray attenuation in underground laboratories Snow water equivalent
In physics, the meter water equivalent (often m.w.e. or mwe) is a standard measure of cosmic ray attenuation in underground laboratories.A laboratory at a depth of 1000 m.w.e is shielded from cosmic rays equivalently to a lab 1,000 m (3,300 ft) below the surface of a body of water.
In 1974, the AWWA established Water as its official journal. [5] It switched to an e-journal format in 2016. [6] The AWA has hosted the annual OzWater conference since 1993. [1] It is a partner in the Department of Foreign Affairs and Trade's Australian Water Partnership, which supports water management initiatives in the Indo-Pacific. [7]
For free flow, the equation to determine the flow rate is simply Q = CH a n where: Q is flowing rate (ft 3 /s) C is the free-flow coefficient for the flume (see Table 1 below) H a is the head at the primary point of measurement (ft) (See Figure 1 above) n varies with flume size (see Table 1 below) Parshall flume discharge table for free flow ...
