Applying the Concepts-Intermediate 1.20 Evaporation from swimming pools. A new formula for es- timating the water evaporation from occupied swimming pools was proposed and analyzed in the journal Heating/ Piping/Air Conditioning Engineering (Apr. 2013). The key components of the new formula are number of pool occupants, area of pool's water surface, and the density e 12
