What approximate weight per US liquid gallon is commonly used for fresh-water load estimates at ordinary temperatures?
Correct Answer
C) 8.34 lb/gal
A common estimate for fresh water is 8.34 pounds per US liquid gallon, as used in EPA WaterSense calculations. Actual density varies with temperature and dissolved material. This is not the value for an Imperial gallon; 7.48 is approximately US gallons per cubic foot, a different conversion.
