Explanation:
To convert the rate of flow from liters per day to cups per hour, we can use the following conversion factors:
1 liter (L) = 33.814 fluid ounces (fl oz)
1 cup (cup) = 8 fluid ounces (fl oz)
1 hour (hr) = 60 minutes (min)
1 day (day) = 24 hours (hr)
First, let's convert liters to fluid ounces:
75 liters * 33.814 fl oz/L = 2536.55 fl oz
Next, let's convert fluid ounces to cups:
2536.55 fl oz * (1 cup/8 fl oz) = 317.07 cups
Finally, let's convert days to hours:
1 day * 24 hr/day = 24 hours
Now, let's calculate the rate of flow in cups per hour:
317.07 cups / 24 hours = 13.21 cups/hour
Rounding to the nearest tenth, the rate of flow is approximately 13.2 cups per hour.
