How many gallons per minute are equivalent to a flow of 1.0 MGD?

To convert million gallons per day (MGD) to gallons per minute (gpm), you can use the relationship that there are 1,440 minutes in a day. Therefore, multiplying 1.0 MGD by the number of gallons in a million (1,000,000) and dividing by 1,440 gives you the flow rate in gpm.

1 MGD = 1,000,000 gallons/day

To convert to gpm:

1,000,000 gallons/day ÷ 1,440 minutes/day ≈ 694.44 gpm

When rounding to the nearest whole number, this value becomes 695 gpm. Thus, the conversion indicates that a flow of 1.0 MGD is equivalent to approximately 695 gallons per minute, validating that the correct answer is 695 gpm. This is important for understanding how to convert between different units of water flow, especially in the context of water treatment and management where different flow rates are often dealt with in design and operational practices.
