What is the formula for calculating flow rate in gallons per minute (GPM)?

The formula for calculating flow rate in gallons per minute (GPM) is correctly represented by dividing the volume of the pool in gallons by the turnover rate in hours and then adjusting for minutes. Since there are 60 minutes in an hour, the calculation involves dividing the total volume by the turnover time in hours, and then dividing that result by 60 to convert the flow rate into gallons per minute.

In practical terms, if you know how many gallons the pool holds and how long it takes to completely cycle that volume, you can determine how many gallons per minute must be circulated. This formula is crucial for ensuring proper filtration and sanitation in the pool, as it helps pool operators manage water quality and turnover rates effectively. This understanding is fundamental for maintaining safe swimming conditions.
