Here we calculate the chlorine dose in mg/l when a chlorinator is set to feed 18 pounds of chlorine in 24 hours. The flow rate is 570,000 gallons per day.

The Davidson pie chart, also referred to by Watersifu as the "dosage" pie chart, is a simpler method to remember dosage calculations. For example, to calculate the dosage, you can use the formula:
18 lbs / 0.57 (which is the same as converting 570,000 to 1,000,000) / 8.34 = 3.375 mg/L.
Using this method can cut the time it takes to solve a basic dosage problem in half.
I still appreciate your approach, as it likely follows the dimensional analysis method used in treatment for calculating dosages. However, please simplify your explanations to make it easier for individuals preparing for entry-level exams.
