A 6,600-gallon commercial spa that operates at a flow rate of 10 gpm has a turnover rate of how many minutes?

To determine the turnover rate for a 6,600-gallon commercial spa operating at a flow rate of 10 gallons per minute (gpm), you can use the formula for turnover rate, which is the total volume of the pool divided by the flow rate.

First, convert the volume from gallons to minutes. The formula to calculate the turnover time in minutes is as follows:

Turnover time (minutes) = Total volume in gallons ÷ Flow rate in gpm.

So, in this case, you would do the calculation:

Turnover time = 6,600 gallons ÷ 10 gpm = 660 minutes.

However, since the question seems to involve finding the turnover as a fraction of the hour, you would need to explain that the turnover rate indicates how long it would take for the spa water to be completely filtered and replaced based on the flow rate.

The options provided appear to reflect an understanding of practical application—the formula gives a turnover time in minutes. Once you arrive at the calculation, dividing by 60 would show the number of hours to achieve complete turnover, which helps clarify why the turnover rate of 660 minutes is critical for maintenance schedules.

Given the calculations of 660 minutes indicating continuous flow results, it's implied the
