The IEEE symbol for the cubic foot per second is ft 3 /s. [1] The following other abbreviations are also sometimes used: ft 3 /sec; cu ft/s; cfs or CFS; cusec; second-feet; The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second.
As the name suggests, an acre-foot is defined as the volume of one acre of surface area to a depth of one foot.. Since an acre is defined as a chain by a furlong (i.e. 66 ft × 660 ft or 20.12 m × 201.17 m), an acre-foot is 43,560 cubic feet (1,233.5 m 3).
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 ...
This article lists the largest lakes, natural and man-made, in the United States by volume—the amount of water they contain under normal conditions. Volumes given for lakes shared with Canada and Mexico are for the total volume of the lake.
It is equal to exactly 43,560 cubic feet, or 325,853.382 U.S. gallons, or 1233.489238 cubic meters". (Unfortunately, it appears that the popular and incorrect calculation of 325,851 or 325,853 gallons per acre foot is being perpetuated throughout the known world! All this because of the lack in ability to do this simple calculation.
The units that are typically used to express discharge in streams or rivers include m 3 /s (cubic meters per second), ft 3 /s (cubic feet per second or cfs) and/or acre-feet per day. [2] A commonly applied methodology for measuring, and estimating, the discharge of a river is based on a simplified form of the continuity equation.
A compact machine with 2.3 cubic feet can wash about 6 towels. Cycles. ... These models use 20-66% less water, saving around 6,000 gallons of water per year for an average family. You may also ...
Volumetric flow rate is defined by the limit [3] = ˙ = =, that is, the flow of volume of fluid V through a surface per unit time t.. Since this is only the time derivative of volume, a scalar quantity, the volumetric flow rate is also a scalar quantity.
