How many million gallons per day is a flow rate of 650 gpm equivalent to?

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

1 gallon = 0.000001 million gallons
1 minute = 1/1440 days (since there are 1440 minutes in a day)

Starting with the flow rate of 650 gpm:

First, convert gallons to million gallons: [ 650 \text{ gpm} \times 0.000001 \text{ million gallons/gallon} = 0.00065 \text{ MGD} ]

Next, convert minutes to days: [ 0.00065 \text{ MGD} \times 1440 \text{ minutes/day} = 0.936 \text{ MGD} ]

Therefore, when you multiply 650 by the number of minutes in a day (1440) and then convert it to million gallons, you arrive at a total of 0.936 million gallons per day, making this the correct answer.
