1 mg/l = 1 ppm (part per million)
Weight of water = 8.34 pounds/ gall
1 mg/l of water = 8.34 pounds / million gallons
Ten parts per million (ppm) is equivalent to 10 gallons of a substance per million gallons of water. This is because "parts per million" denotes a ratio of one part of a substance to one million parts of the solution. Therefore, 10 ppm means there are 10 gallons of the substance in every million gallons of the solution.
147.36 million gallons per day.
1.29 million gallons per day equates to two (2) cubic feet per second.
1 million gallons per day equates to about 0.001522472 cubic feet per second.
You cannot do that. Do you mean gallons per second to hours?
429,315 million gallons
To find the concentration in parts per million (ppm), you would need to calculate the ratio of chlorine to water. In this case, to determine the concentration of 5 gallons of chlorine in 1 million gallons of water, you could use the following calculation: (5 gallons chlorine / 1 million gallons water) x 1,000,000 = 5 ppm.
In very rough numbers, we have about 25 million autos each burning about 2 - 3 gallons per day average. This would lead to the figure 50 to 75 million gallons of gasoline per day. An official figure of 1.2 billion gallons was released in a recent month. Divide by 30 days to get "only" 40 million gallons per day.
That's simple arithmetics: 14 million gallons per day is 14 million gallons per 86400 seconds, so it's about 162 gallons per second. 162 gallons is about 21.66 cubic feet. Divide that by the area of channel section of 500 square feet and you get about 0.043 feet/second.
the average discharge is 680,000 gallons of water per second.
About 142.5 billion gallons of gasoline are used each year in the United States. This represents 392 million gallons per day. This is based on an estimated figure of 9.12 million barrels per day, 43 gallons per barrel, 365 days in a year.
750 million gallons (US) is 2.301.4 acre-feet.
