Final answer:
The flow of the river is 12.884144 liters per second and 406,086,752 liters per year after conversion from cubic feet per second.
Step-by-step explanation:
To convert the flow rate from cubic feet per second (ft³/s) to liters per second (L/s), we can use the conversion factor that 1 cubic foot equals approximately 28.3168 liters.
The given flow rate is 0.455 ft³/s.
Therefore:
Flow in L/s = 0.455 ft³/s × 28.3168 L/ft³
= 12.884144 L/s
Next, to find flow rate in liters per year (L/yr),
we multiply the rate by the number of seconds in a year (60 seconds/min × 60 minutes/hour × 24 hours/day × 365 days/year):
Flow in L/yr = 12.884144 L/s × 60 × 60 × 24 × 365
= 406,086,752 L/yr
