Question

water flows through a pipe at a rate of 540 milliliters per day. express this rate of flow in pints per year. round your answer to the nearest whole number.
*note: you must use these exact conversion factors to get this question right.

volume	time
1 pint (pt) = 2 cups (cups)	1 hour (hr) = 60 minutes (min)
1 quart (qt) = 2 pints (pt)	1 day (day) = 24 hours (hr)
1 gallon (gal) = 4 quarts (qt)	1 week (week) = 7 days (days)
1 cubic foot (ft³) = 7.481 gallons (gal)	1 month (month) = 30 days (days)
1 liter (l) = 1000 milliliters (ml)	1 year (year) = 365 days (days)

Explanation:

Step1: Convert milliliters to liters

We know that 1 liter = 1000 milliliters. So, 540 milliliters per day is $\frac{540}{1000}=0.54$ liters per day.

Step2: Convert liters to fluid - ounces

1 liter is approximately 33.814 fluid - ounces. So, 0.54 liters per day is $0.54\times33.814 = 18.25956$ fluid - ounces per day.

Step3: Convert fluid - ounces to cups

Since 1 cup = 8 fluid - ounces, then 18.25956 fluid - ounces per day is $\frac{18.25956}{8}=2.282445$ cups per day.

Step4: Convert cups to pints

Since 1 pint = 2 cups, then 2.282445 cups per day is $\frac{2.282445}{2}=1.1412225$ pints per day.

Step5: Convert pints per day to pints per year

Since 1 year = 365 days, then the rate is $1.1412225\times365 = 416.5462125\approx417$ pints per year.
