To achieve a 6 hour turnover rate in a pool that holds 33,000 gallons of water, what flow rate in gallons per minute (GPM) is needed?

• A. 85 GPM
• B. 92 GPM
• C. 100 GPM
• D. 110 GPM

Answer: (B)

To determine the flow rate necessary for achieving a 6-hour turnover rate in a pool with a volume of 33,000 gallons, you'll start by calculating the total gallons that need to be circulated in that time frame. Since turnover refers to the complete circulation of the pool's volume, for a 6-hour turnover, you'll need to process 33,000 gallons in that time. Next, you'll convert the turnover time from hours to minutes. Since there are 60 minutes in an hour, a 6-hour period translates to 360 minutes. Now, to find the required flow rate in gallons per minute (GPM), you can use the formula: Flow rate (GPM) = Total gallons to circulate / Total minutes for circulation. Plugging in the numbers: Flow rate (GPM) = 33,000 gallons / 360 minutes, which calculates to approximately 91.67 GPM. Rounding this number, the closest practical flow rate needed to achieve the desired 6-hour turnover is 92 GPM. This value aligns correctly with the calculations and the standards for flow rates in pool operation, confirming it as the proper answer.
