Question

please helpOn average, water flows over a particular water fall at a rate of 2.04 x 105 cubic feet per second. One cubic foot of water weighs 62.4 lb. Calculate the rate of water flow in tons of water per day. (1 ton = 2200 lb)

Answer 1

starting with 2.04 x 10^5 cubic feet per second,

The problem says that 1 cubic foot of water weighs 62.4lbs, so multiply by 2.04* 10^5 cubic feet by 62.4lbs.

Now, in one day there are 24 hours, 60 minutes per hour, 60 seconds per minute, so multiply the previous quantity by 24 * 60 * 60 to get the flow in lbs per day.

Finally, it wants the answer in tons. Since 1 ton = 2200 lbs, divide by 2200.
