A garden hose has a water flow rate of 11.00 liters per minute. How long will it take to fill an 8 foot x 10 foot swimming pool to a depth of 4.50 feet?

Question

1 liter = 0.26417 gal, and 1 cubic foot = 7.4805 gal.

Answer 1

Given:

1 L = 0.26417 gal and 1 cubic foot = 7.4805 gal

Garden Hose Water Flow Rate = 11 L/min

Volume of Swimming Pool: 8 ft * 10 ft * 4.50 ft = 36,000 ft³

36,000 ft³ * (7.4805 gal/1 ft³) = 269.298 gal = 270 gal

270 gal * (1 L/0.26417 gal) = 1022.069 L = 1022 L

1022 L * (1 min/11 L) = 92.9 min

It will take 92.9 min to fill an 8 ft x 10 ft x 4.5 ft swimming pool.
