Hot
days are a pain, but they make for a great time to take a dip. A pool
can beat the heat as long as the heat doesn't beat the pool first.
Where
there's water and heat, there's bound to be a drop in water levels;
pools, reservoirs, you name it. Water loss from a pool depends on the
pool size, humidity, temperature, and wind velocity. A 500
square-meter pool in 77-degree weather and 50 percent humidity may
lose 49 ml of water a second. A minute later, it may lose as much as
three liters.
