A flow of 1.55 ft³ per second is equivalent to how many gallons per minute (gpm)?

To convert a flow rate from cubic feet per second (ft³/s) to gallons per minute (gpm), it is essential to utilize the conversion factors that relate these two units.

When converting, the first step is to recognize that there are 7.48 gallons in a cubic foot. Therefore, to find out how many gallons are in 1.55 cubic feet, you multiply 1.55 by 7.48. This calculation gives you the total number of gallons per second.

Next, since the question asks for gallons per minute, you need to convert the flow from gallons per second to gallons per minute. There are 60 seconds in a minute, so you multiply the gallons per second result by 60.

Putting it all together, the calculation would look something like this:

1.55 ft³/s × 7.48 gallons/ft³ = total gallons per second

(total gallons per second) × 60 seconds/minute = total gallons per minute

Performing these calculations gives:

1.55 × 7.48 ≈ 11.586 gallons per second,

and then,

11.586 gallons/second × 60 seconds/minute ≈ 695.16 gallons per minute.
