Water flowing over a particular waterfall at a rate of 2.02 x 10⁵ ft³/s is equivalent to 4.95 × 10⁸ ton/day.

First, we will convert 2.02 x 10⁵ ft³/s to ton/s using the following conversion factors:

Then, we will convert  5.73 × 10³ ton/s to ton/day using the following conversion factors:

Water flowing over a particular waterfall at a rate of 2.02 x 10⁵ ft³/s is equivalent to 4.95 × 10⁸ ton/day.

Approximately 5.00 × 10⁸ tons per day. (Rounding error: less than 1.1%.)

Explanation:

How many cubic feet of water flows over this waterfall each day?

The question gives only the number of cubic feet of water that flows over each second. To find the volume for each day, start by finding the number of seconds in a day.

There are 60 seconds in a minute and 60 minutes in an hour. That translates to seconds in an hour.

There are 24 hours in a day. Each hour contains seconds. That means that there are seconds in a day.

cubic feet of water flows over this waterfall every second. Therefore, cubic feet of water flows over this waterfall every day.

The weight of one cubic foot of water is pounds. The weight of of cubic feet of water will be pounds.

It takes 2,200 pounds to make a ton.   will translate to tons.

To calculate the rounding error, evaluate

and drop the negative sign if there is one. Rounding the final result to gives a rounding error of approximately .

the answer is 0.8m.
