The Colorado River is diverted to flood fields. If the river is flowing at 17,600 ft3/s , how long will it take to flood a 5500 acre field to a depth of 2.00 meters? Note that 1 acre=43560ft2.
This looks like math to me.
5500 acre * 43560ft^2 * 2m * 3.28ft/m * 1s/17600ft^3
= 5500*43560*2*3.28/17600 = 89298s
one day is 86400 seconds
To find out how long it will take to flood the field, we need to calculate the volume of water required and then divide it by the flow rate of the river.
First, let's calculate the area of the field in square feet:
5500 acres * 43560 ft²/acre = 239,580,000 ft²
Next, let's convert the depth from meters to feet:
2.00 meters * 3.28084 ft/meter = 6.56168 ft
Now, let's calculate the volume of water required in cubic feet:
239,580,000 ft² * 6.56168 ft = 1,573,289,372.1152 ft³
Finally, we can determine the time it will take to flood the field by dividing the volume of water required by the flow rate of the river:
1,573,289,372.1152 ft³ / 17,600 ft³/s = 89,253.86 s
Therefore, it will take approximately 89,253.86 seconds to flood the 5500-acre field to a depth of 2.00 meters.
