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
Multiply cubic feet per second by 60 to get cubic feet per minute.
cubic feet per second x 60 = 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)
12.4 litres =3.276 US Gallons2.728 Imperial Gallons
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.
