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

The rate is 2.04x10^5 cubic feet per second
There are 86,400 seconds in a day. (60*60*24)
So the flow rate per day is
2.04x10^5 * 86,400 =
17,625,600,000 cubic feet per day
17,625,600,000 * 62.4 makes that equal
1,099,837,440,000 pounds per day
Dividing that by 2,200 makes that equal
499,926,109 tons per day
(Incidentally, that is long tons)
You said 2,200 pounds = a ton (a LONG ton actually)
Usually a ton is stated as 2,000 pounds.
