If the projected water use for a new subdivision is 3.1 million gallons per day (mgd), what is the equivalent in gallons per minute (GPM)?

2152 GPM
3000 GPM
2400 GPM
1800 GPM

The correct answer is: 2152 GPM

To convert the projected water use from million gallons per day (mgd) to gallons per minute (GPM), you will need to know the relationship between these two units. 1 million gallons (mg) is equivalent to 1,000,000 gallons. There are 1,440 minutes in a day (24 hours x 60 minutes). To find the conversion factor from mgd to GPM, you multiply by the conversion from millions to gallons and then divide by the number of minutes in a day. Here's the calculation for 3.1 mgd: - First, convert million gallons to gallons: 3.1 mgd = 3.1 x 1,000,000 = 3,100,000 gallons. - Next, convert gallons per day to gallons per minute: 3,100,000 gallons per day ÷ 1,440 minutes per day = approximately 2,152.78 GPM. Rounding this to the nearest whole number gives 2,152 GPM. This calculation demonstrates that option A is the correct answer, accurately reflecting the conversion from mgd to GPM.
