If a water treatment plant receives an average flow of 261 gpm, what is the daily total flow to the plant in mgd?

To convert the average flow rate from gallons per minute (gpm) to million gallons per day (mgd), you can use the following conversion factors:

1. There are 60 minutes in an hour, so you multiply the flow rate (in gpm) by 60 to get gallons per hour.
2. Then, you multiply by 24 to convert from hours to days, as there are 24 hours in a day.
3. Finally, since mgd stands for million gallons per day, you will divide the total gallons per day by 1,000,000.

Starting with an average flow of 261 gpm:

1. Convert to gallons per hour: 261 gpm × 60 minutes/hour = 15,660 gallons/hour.

2. Convert to gallons per day: 15,660 gallons/hour × 24 hours/day = 375,840 gallons/day.

3. Convert to mgd: 375,840 gallons/day ÷ 1,000,000 = 0.37584 mgd.

When rounded to two decimal places, this value is approximately 0.38 mgd. Therefore, this calculation aligns with the option given, confirming that the correct daily total
