The level of water in an Olympic size swimming pool (50.0 meters long, 25.0 meters wide, and about 2 meters deep) needs to be lowered 3.2 cm. If the water is pumped out at a rate of 5.0 liters per second, how long will it take to lower the water level 3.2 cm?

Answer 1

volume of water to be removed is
5000 cm x 2500 cm x 3.2 cm = approx 4E7 cc
Convert to ? L
Then 5.0 L/sec x #sec = ? L.
Sole for #sec.
