1 gallon = 231 cubic inches
1 cubic foot = 1,728 cubic inches
1 minute = 60 seconds
20 gallons per minute = (20 x 231) cubic inches per minute = (20 x 231 / 60) cubic inches per second
= (20 x 231 / 60) / 1,728 cubic feet per second
= 0.04456 cubic feet per second (rounded)
6,000 US gallons per minute = 13.37 cubic feet per second.
Use this formula to convert gallons per minute to cubic feet per second:gallons per minute x 0.002228 = cubic feet per second. So; 500 x 0.002228 = about 1.114 cubic feet per second.
20 US gallons per minute = 2.674 cubic feet per minute.
For US gallons, use this equation: gallons per minute x 8.020833333 = cubic feet per hour750 gallons/minute x 8.020833333 = about 6,015.625 cubic feet per hour
cubic feet per second x 60 = cubic feet per minute
Multiply cubic feet per second by 60 to get cubic feet per minute.
One cubic foot per minute = 7.481 US gallons per minute.
A water flow of 1,400 cubic feet per second equates to approximately 628,363.64 US gallons per minute.
Formula: cubic feet per hour x 7.481 = US gallons per hour (use 6.229 if you want to convert cubic feet to Imperial gallons)
12000 gallons of water is equivalent to 1600 cubic feet.
The flow rate in cubic feet/second is (3*1.5*3) = 14.5 cubic ft/sec. According to Google, there are 6.229 Imperial gallons or 7.481 US gallons in 1 cubic foot. Therefore, the flow rate is 90.32 Imp gallons/sec or 108.47 US gallons/sec. If this many gallons flow per second, then (90.32 x 60) = 5419 Imp gallons flow per 1 minute, or equivalently 6508 US gallons per minute.
4,100 cubic feet per second equates to approximately 30,670.13 US gallons per second.
