There are two difficult aspects to this problem, specific gravity, and the percentage of alum in the solution.

Math Constant: Specific gravity of water = 1

Math Constant: 1 gram of water = 1mL

11.25 gallons of 8% polymer

this problem could be a bit confusing because the 150 gallons has less than 1% polymer

Step 1: convert percentages to usable numbers 0.6%=0.006 and 8%=0.08

Step 2: how much polymer is in the solution? 150 gal x 0.006 = 0.9 gallons of polymer in the...

The correct answer to this item is letter D. To get the surface area of a circle, one must use the formula r squared multiply by pi. Since the radius is not given, divide the diameter by 2. So, 55 ft divided by 2 is 27.5 and this will be the radius.

Next, multiply 27.5 by 27.5 and the...

mg/l and ppm are the same

1.6 million gallons x 8.34lbs per gallon = 13.344 million pounds, so 13.344 is 1ppm of 1.6 million gallons

28lbs / 13.344 =2.0983213 rounded to 2.1
