What is the resultant turnover time for a spa of 3,500 gallons with a flow rate of 150 gpm?

To determine the resultant turnover time for a spa, you can use the formula:

[

\text{Turnover Time} = \frac{\text{Volume of Water}}{\text{Flow Rate}}

]

In this scenario, the spa has a volume of 3,500 gallons and a flow rate of 150 gallons per minute (gpm). Plugging these values into the formula gives:

[

\text{Turnover Time} = \frac{3,500 \text{ gallons}}{150 \text{ gpm}} = 23.33 \text{ minutes}

]

This calculation results in approximately 23.3 minutes when rounded to one decimal place. Turnover time is critical in pool and spa maintenance because it indicates the time taken for the entire volume of water to pass through the filtration system, ensuring adequate circulation and sanitation. Thus, the correct answer reflects the time required for the system to efficiently filter and clean the spa's water. This information is essential for understanding how often the water is refreshed, which impacts water quality and clarity in pool and spa management.
