Answer: 417.3926 pints per year
Explanation:
To convert mililiters to pints, we need to know that 1 mililiter is equal to 0.00211338 pints (rounded to eight decimal places).
So, 540 mililiters per day is equal to:
540 x 0.00211338 = 1.1427212 pints per day
To express this rate in pints per year, we need to multiply by the number of days in a year:
1.1427212 pints per day x 365 days per year = 417.3926 pints per year
Therefore, the rate of water flow is 417.3926 pints per year.
