Answer 5

how did you figure it out though?

Answer 6

I looked for niagara water flow in the net
actually in spanish water flow is one word "caudal" so, "niagara caudal"

Answer 7

that is the right answer! thank you so much!!

Answer 8

can you please help me with a follow up question: The falls provides the outlet for Lake Erie; if the falls were shut off, estimate how long it would take Lake Erie to rise 1m .

Answer 9

Check for Lake Erie surface area in m^2, multiply by a meter depth = total volume raised. And by answer B, divide the lake volume by the river flow so the only unit remaining is seconds.

Answer 10

25745Km^2 area of Lake Erie, to square meters is that times a million. For one meter deep volume is 25,745,000,000 m^3

Answer 11

8581667s = 143028min = 2384h = 99.32days = 3.3month

Answer 12

That was using your value of 3000m^3/s

Answer 13

thank you :)

Answer 14

how did you get the seconds? how did you get 8581667?

Answer 15

25,745,000,000m^3 lake volume 1 meter high divided by 3000m^3/second of your answer = time in seconds (8581667sec rounded) if divided by 60sec/min (143028min) if divided by 60min/hour (2384hours) if divided by 24hour/day (99.32days) if divide by 30days/month (3.3month).
All values are rounded as they are but always from the original (carrying all numbers) amount.

Answer 16

aaah I see thank you so much!!
