Water in a storage tank 25 feet in diameter and 30 ft deep rises 1.8 feet in one hour.
:
Find the no. of hrs to fill at 1.8 ft/hr rise
30%2F1.8 = 162%2F3 hrs
:
Find the number gallons in the full tank (g); (7.481 gal in 1 cu/ft)
g = pi%2A12.5%5E2%2A30%2A7.481
g = 110,167 gallons
:
What is the Gallons per Minute (GPM) flow into the tank.
change 162%2F3 hrs to minutes: 60*16,66667 = 1000 minutes
110166.8%2F1000 ~ 110 gal/min
How long will it take to fill from empty? 16 hrs, 40 min
