Volume and WeightOne inch of rain falling on 1 acre of floor is equal to around 27,154 gallons and also weighs around 113 tons.An inch of snow falling evenly on 1 acre of floor is identical to around 2,715 gallons of water. This figure, however, based upon the "rule-of-thumb" the 10 customs of eye is same to 1 inch of water, have the right to vary considerable, depending on whether the eye is heavy and also wet, or powdery and also dry. Heavy, wet snow has actually a really high water content--4 or 5 customs of this sort of eye contains around 1 inch of water. Thus, an inch of really wet snow over an acre might amount to an ext than 5,400 gallons that water, if an customs of powdery snow can yield only around 1,300 gallons.One acre-foot of water (the quantity of water spanning 1 acre to a depth the 1 foot) equates to 326,000 gallons or 43,560 cubic feet of water, and weighs 2.7 million pounds.One cubic mile of water equals 1.1 trillion gallons, 147.2 exchange rate cubic feet, or 3.38 million acre-feet, and weighs 9.2 trillion pounds (4.6 billion tons).Rate of circulation (in a stream)· Water flow at the steady price of 1 gallon per minute is identical to: 1,440 gallons every day; 0.00223 cubic foot per second; 192.7 cubic feet per day; or 0.00442 acre-foot that water per day.· Water flowing at the steady price of 1 cubic foot per second is identical to: 449 gallons every minute; 646,000 gallons every day; 86,400 cubic feet every day; or 1.98 acre-feet that water every day.· Water flow at the steady rate of 1 acre-foot per day is identical to: 226 gallons per minute; 326,000 gallons every day; 0.504 cubic foot every second; or 43, 560 cubic feet that water every day.· Water flow at the steady rate of 1 cubic mile every day is tantamount to: 764.6 million gallons per minute; 1.1 trillion gallons every day; 1.7 million cubic feet per day; or 3.38 million acre-feet that water every day.Water Equivalents1 cubic foot = 7.48 gallons = 62.4 pounds 100 cubic feet = 1 ccf (std. Bill unit) = 748 gallons 1 acre-foot* = 43,560 cubic feet = 325,900 gallons 1 cubic foot per second (cfs) = 450 gallons per minute 1 cfs = 646,320 gallons every day 1 cfs because that 24 hrs = 1.983 acre-feet 1 cfs for 30 work = 59.5 acre-feet 1 cfs for one year = 724 acre-feet 1 million gallons = 3.07 acre feet 1 million gallons per day (mgd) = 1,120 acre feet per year 1000 gallons every minute = 2.23 cfs 1000 gallons every minute = 4.42 acre-feet every day Metric Equivalents 15 million gallons every day (mgd) = 56.775 megaliters pr job (ML/day) 1 acre = .004 square kilometers (km) 78,000 acres = 312 square kilometers (km) 120 square mile = 193.08 square kilometers 1 acre foot = 1.233 million liters = 1.233 megaliters 1 ccf (one hundred cubic feet) or 748 gallons = 2832 liters = 2.832 cubic meter 250 miles = 402.25 kilometers 450 mile = 724.05 kilometers 1 gallon per minute (gmp) = 3.78 liters every minute 1 pound per square customs (psi) = 0.07031 kg/sq.
