Pevapo. = (25+19Vw) x S x (X - X') x Lv x t/1000

with:

Pevapo: evaporation losses (kWh)

25 + 19Vv: empirical formula giving the ratio of the heat exchange coefficient hconv by convection between the water and air (W / m²K) on the Cair specific heat of air (= 0,277Wh / kg of air.K)

Vw: wind speed (m / s)

S: the pool surface (m²)

X: specific humidity of saturated air at the temperature of the water (g water / kg air)

X ': specific humidity of ambient air at the temperature of the water (g water / kg air)

Lv: enthalpy (or latent heat) of vaporization of water: 0.625 Wh / g

t: time without solar cover (in hours)
