Factors that generally affect evaporation are mainly temperature, humidity, liquid surface area and air flow velocity at the liquid surface. Whereas under relatively quiescent conditions, the rate of water evaporation is dependent only on the rate of molecular diffusion, and the rate of evaporation W is described by the following equation:
