00:00 - Intro02:21 - Evaporation is the process of liquid water converting into water vapor (gas). And this process takes energy (heat) to occur.03:40 - Humidity in the air and the difference between air and water temperature (delta T) are the two main factors that determine evaporation rate.05:03 - How evaporation affects water chemistry.  An average pool loses roughly its entire volume of pool water in a given year.06:28 - Difference in temperature between water and air matters a lot. Cold air and warm water evaporates more. 08:58 - Anything in tap water tends to accumulate over time (calcium, metals, etc.). Things not in tap water tend to stay consistent (CYA, salinity, etc.)10:34 - https://blog.orendatech.com/evaporation-and-accumulation11:27 - Evaporation scum/scale line on their tile, above the waterline. Not necessarily an LSI violation, because water leaves, so the saturation of CaCO3 goes up.14:21 - Winterization involves draining water down, and the dilution throughout the winter drastically changes water chemistry.16:52 - Analogy: glass of water. CH = 200 ppm.  Drink half, the CH does not change.  Let half evaporate, and the CH doubles.18:19 - Thanks for listening! ------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/
