USEFUL RULES.
To Ascertain the Weight of a Given Number of Gallons of a Liquid, multiply 8.33 by the specific gravity of the liquid, and the product by the number of gallons. For instance, suppose we have 1000 gallons of a must which shows 22 per cent. sugar. From Table I we obtain the corresponding specific gravity, 1.0923 (the figure 1 is omitted except at the top of the column), which shows how much heavier it is than water, water being 1. Now, one gallon of water at 60° F. weighs 8.33 lbs., and the temperature of the must should be about the same. (See [Must—Testing for Sugar].) 8.33 multiplied by 1.0923 = nearly 9.1, which is the weight in pounds of one gallon of the must. One thousand gallons would weigh nearly 9,100 lbs. If Beaumé’s hydrometer is used, ascertain from Table II the specific gravity corresponding to the mark on the stem. This rule applies to all liquids whose specific gravity is known—syrup, wine, brandy, alcohol, etc.
