Water Evaporation from a Pool
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 loss.
Here are more opinions and answers:
Take a 5-gallon bucket and make a mark with a permanent marker at about the halfway point. Fill the bucket with water up to that point, and set the bucket right beside your swimming pool. Simultaneously, use a pencil to mark the water level on your pool tile. In that way, your can determine how much water has evaporated from the bucket and from the pool.
I am sure there are a lot of variables regarding geographic location and humidity levels. In the Mid-Atlantic, I would consider anything over 1/2" per day the mark to start looking for problems (unless you have a heated spa or waterfall, etc.).
What size is the pool? Where do you live? How much average rainfall do you get? How hot is the area? I live in South LA. We haven't received any rain here in the month of June. I'm having to constantly add water to keep the level above the skimmer line. It takes an hour to two hours to simply add an inch of water back to my pool. What a water bill!

This depends on many factors.

nearly none but most of the water might freeze.
If you wait long enough, all of it!
You need to replace the water that evaporates.
Eventually, all of it if not replenished. The rate of evaporation depends on local climatic conditions.
This depends on the solute in water.

Yes, clean water is evaporated faster.
Water evaporates. The hotter the surface temperature is, the faster the evaporation rate it. Even during the summer, the water evaporates at night.
Salt water is evaporated slowest.
