Answer 1

Answer #1

Give water flowed per day=9,000,000,000 gallons per days

a)

Converting gallons into cubic foot = 9,000,000,000/7.5=120,000,000 cubic foot per day

Converting day in seconds=24*60*60=86,400

Therefore flow rate cubic foot per second will be = 120,000,000/86400=1388.888

b)

Given area = 6 square miles

Converting area into square foot = 6*5280*5280=167,270,400 square foot

Total flow per day in cubic foot = 120,000,000

Water level rise per day will be = 120,000,000/167,270,400=0.7174

There water level rise per day will be 0.7174 foot

Hurricane Katrina has devastated New Orleans. Following the hurricane, which in itself did not do as much damage as some had feared, the levees that protect the city broke, and the city was immediately flooded. Many families, especially in Ward Nine and others of the poorer districts, were stranded by the flood and in terrible danger—from drowning, from disease (there was no potable water), from hunger, from lack of access to health care, and eventually, from roving gangs. Somehow, they...
