To convert gallons per day to milliliters per minute, start by recognizing the necessary conversion factors.

First, convert gallons to milliliters. There are approximately 3,785.41 milliliters in a gallon. So, for 26.3 gallons, the calculation is:

26.3 gallons × 3,785.41 mL/gallon = 99,698.1 mL/day.

Next, convert the daily flow rate to a per-minute flow rate. There are 1,440 minutes in a day (24 hours × 60 minutes). To get the flow rate in mL/min:

99,698.1 mL/day ÷ 1,440 minutes/day = approximately 69.1 mL/min.

This calculation shows that the flow rate of 26.3 gallons per day converts to about 69.1 mL/min, confirming that this is the correct answer.

Understanding these conversions is crucial in water treatment operations, where precise dosing and chemical metering affect overall system performance and efficiency.
