At 1 gps (gallon per second), which translates into 60 gpm ((*60)gallons per minute), 3600 gph ((*60)gallons per hour), and 86400 (*24 hours in a day) gallons per day, 400000 gallons could be filled in 400,000 gal / 86,400 gal days, or 4.63 days.
694.4days
about 4.6 days because there are 86400 seconds in a day and if you take 400000/86400 you get 4.629...
7.42 cubic feet/second = 55.51 gallons/second [US].
4.4 US gallons per second.
5.750 (US gallons per hour) = 0.00604614382 liters per second.
25 miles per gallon (first choice) is better than 23 miles per gallon (second choice).
(1 US gallon/hour) x (1 hour/3,600 seconds) x (3.78541 liters/US gallon) = 0.0010515liter/second(rounded)
How large is the aquarium? If its around 60 gallons, the answer is no if you live in a normal housing structure. Some people have had water beds on the second floor of a house without any problems. If you are overly concerned about this, you may already have a good feel for the answer.
One gallon per minute is 0.267 cups per second. Therefore, 3.5 gallons per minute = 3.5 x 0.267 = about one (0.9345) cup per second.
Gallons per minute is the amount of gallons used or moved or saved for every minute of time that passes. If you wanted to calculate how many gallons were pumped through a water fountain every minute, you would measure this and divide the gallons by the minutes and get your "gallons per minute".
8 qt = 1 gallon 60 seconds = 1 minute 2 qt/min = 2qt/60 sec = 1/30 qt/sec = 1/30 (1/8 gallon)/sec = 1/240 gallons/sec ≈ 0.0042 gallons/sec
I had to look this one up. A cusec means a flow rate of 1 cubic foot per second. So you wound need to ask gallons per (unit of time). 1 cubic foot = 7.48052 gallons. If you want gallons per second, then the answer is 7.48052 gallons per second. A common term with pumps is gallons per minute, so if you want that: (7.48052 gal/sec) * (60 sec/minute) = 448.831 gallons per minute.
