How much water evaporates from a swimming pool per day?

Answer 1

I live in Southern Arizona and right now it's hot and dry (110F with 10% humidity). I lose about an inch of water every three days. My pool is 24 feet by 14 feet so that works out to about 70 gallons per day!!

Answer 2

That is a question loaded with variables. How many gallons in the pool? What is the temperature outside? What is the temperature of the water? Is there a solar blanket on the pool? How about bather load? (# of swimmers per hour)

Answer 3

The evaporation rate depends on the surface area of the pool, the temperature, and the relative humidity and the wind. I'm sure an "equation" containing the variables is known. Perhaps a civil or mechanical engineer would have a specific equation. I did find what seems to be a credible source that provides a reasonable answer. Here is the link: Marin municipal water district. They have a chart that lists 200-300 gallons per week for a medium-sized pool -- about 2%-5% of typical pool volumes. "Splash-out" water is probably a much more significant source of water

Answer 4

It depends on the surface size, temperature of the water and outside air temperature, the activity in the water, if there are any water features in the pool etc.

Answer 5

This depends on the surface area of the pool but generally speaking on a really hot day with a pool that is heated to 85F you can loose up to 1/4 inch of water a day.

Answer 6

¹00%

Answer 7

ten gallons
