    Hence evaporation and condensation are two generating processes that are reversed. 3.7.1 Falling Film Evaporation on Vertical Plate. Falling film evaporation is the same as the process of falling film condensation essentially, but the different generating direction is reversed. However, they are different in practical industrial application.

    Evaporation is the process in which a liquid changes to the gaseous state as the free surface, below its boiling point, through the transfer of energy. Evaporation is a cooling process- the latent heat of vapourisation (~585 cal/g of evaporated water) must be provided by the water body. Rate of evaporation depends on.
