What flow rate in GPM (Gallons Per Minute) would be needed to achieve a 6-hour Turnover Rate (TOR) for a pool that has 33,000 gallons of water?

55 GPM
75 GPM
92 GPM
105 GPM

The correct answer is: 55 GPM

A 6-hour Turnover Rate (TOR) means that the entire volume of the pool needs to be circulated every 6 hours. Since the pool has 33,000 gallons of water, we need to divide this by 6 to determine the flow rate in GPM. This gives us a flow rate of 5,500 GPH (gallons per hour). To convert to GPM, we divide by 60, giving us a flow rate of 91.67 GPM. However, since we want to achieve this flow rate in 6 hours, we need to divide by 6, giving us a flow rate of 15.28 GPM. Option A is the closest and most accurate answer, as it is the only option that is less than the calculated 15.28 GPM. The other options would result in a turnover rate that is either too slow or too fast.
