How much is a miners inch?
A Miner’s Inch is a measure for flow of water, and is the quantity of water that will flow in one minute through an opening one inch square in a plank 2 inches thick under a head of 6.5 inches to the center of the orifice. This is equivalent, approximately to 1.2 cubic feet, or 9 gallons per minute.
How many gallons are in a cfs?
Cubic feet per second (cfs): * 1 cubic foot per second = 7.4805 gallons flowing by a particular point in 1 second. * 1 cfs = 1.983 acre-feet per day = 646,320 gallons = 2447 cubic meters of water. * 1 cfs is equivalent to 448.8 gallons of water flowing per minute.
How many gallons are in a inch miner?
11.22 gallons
NID irrigation water is measured by the miner’s-inch, a historic water measurement that goes back to the Gold Rush. A miner’s-inch equals 11.22 gallons per minute, on a 24-hour per day basis.
What are miners inches of water?
A miner’s inch represents the rate of water flow in a miner’s sluice through an orifice one inch square, or one-inch in diameter, through a two-inch thick plank with a head of six inches. This single orifice was limited to low flows in the range of 1.5 cubic feet per minute (11.25 gallons per minute).
What is a miner’s inch used for?
The miner’s inch is a unit of flow in terms of volume per unit time, usually in relation to the flow of water. 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.
What is cusec water?
28.32 litres
Cusec is a measure of the rate of flow still commonly used by the irrigation department. 1 cusec is one cubic foot of water flow per second. It translates into 28.32 litres of water per second.
How many feet deep is an acre?
Definitions. 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 m3).
How many acres are 100 miner’s inches?
100 California miner’s inches for one day equal 4.96 acre-feet. 100 Colorado miner’s inches equal 2.60 second-feet. 100 Colorado miner’s inches equal 19.5 United States gallons per second. 100 Colorado miner’s inches equal 104 California miner’s inches.
What is a miner’s inch?
Generally, one miner’s inch is a flow of 1.5 cubic feet per minute You will find references to “miner’s inches” in old water right filings and notices, as well as older decrees governing water rights.
How do you measure the flow of a miners inch?
The lower edge of the aperture should be 2 ins. above the bottom of the measuring-box, and the plank 5 ins. high above the aperture, thus making a 6 in. head above the centre of the stream. Each square inch of this opening represents a miner’s inch, which is equal to a flow of 1½ cu. ft. per min.
Why was the miner’s inch replaced by cubic feet per second?
As water demand increased with the development of large-scale mining technologies and the development of irrigation uses, the miner’s inch became an inadequate unit of measurement for flow rates, and was replaced by cubic feet per second.
