A swimming pool with a capacity of 80,000 gallons requires an eight-hour turnover. What is the necessary flow rate in gallons per minute?

To determine the necessary flow rate in gallons per minute (gpm) for a swimming pool with a capacity of 80,000 gallons and a required turnover time of eight hours, you need to follow a straightforward calculation.

First, you convert the turnover time from hours to minutes. Since there are 60 minutes in one hour, an eight-hour turnover equals 8 hours × 60 minutes/hour, which is 480 minutes.

Next, to find the flow rate, you divide the total pool volume by the turnover time in minutes:

Flow Rate = Total Volume / Turnover Time in minutes

Flow Rate = 80,000 gallons / 480 minutes

Calculating this gives:

Flow Rate = 166.67 gallons per minute.

When rounding to a whole number for practical purposes, this value is typically rounded to 167 gpm. Therefore, the correct answer is indeed 167 gpm, which aligns with the calculated requirement for efficient and effective water circulation in the pool.

This flow rate ensures that all the water in the pool is adequately filtered and treated within the designated turnover time, maintaining water quality and safety for swimmers.
