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.
The acre-foot per year has been used historically in the US in many water-management agreements, for example the Colorado River Compact, which divides 15 million acre-feet per year (19 cubic kilometres per year) among seven western US states. Water reservoir capacities in the US are commonly given in thousands of acre-feet, abbreviated TAF or KAF.
The rate of flow is typically expressed in units of cubic meters per second (m³/s) or cubic feet per second (cfs). Hydrographs often relate changes of precipitation to changes in discharge over time. [3] The term can also refer to a graph showing the volume of water reaching a particular outfall, or location in a
The area required to calculate the volumetric flow rate is real or imaginary, flat or curved, either as a cross-sectional area or a surface. The vector area is a combination of the magnitude of the area through which the volume passes through, A , and a unit vector normal to the area, n ^ {\displaystyle {\hat {\mathbf {n} }}} .
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
All this because of the lack in ability to do this simple calculation. I will illustrate here: 1 acre (1 foot thick) x # of gallons in a cubic foot. This is, simply 43560 (Cubic feet) x 7.48 gallons / cubic foot = 325,828.8 gallons - rounded to 325,829 gallons per acre foot (do it on a calculator!).
Beginning on March 9, irrigation and residential customers who use more than 10,000 cubic feet of water per month will be billed at a new Tier 4 rate. "We don't want your money.
22,956.841139 acre feet 6.228835459×10 9 imperial gallons Alternatively, 35.32 tmcft = 1 cubic kilometer (km 3 ) is the standard unit used by Central Water Commission of Government of India for reporting gross and effective storage capacities of dams in India in National Register of Large Dams (NRLD).
