New data have been obtained on vaporization of water from rippling and nonrippling films in a countercurrent wetted‐wall tower. Other similar data in the literature have been analyzed, and an effect of liquid Reynolds number on gas phase mass transfer has been shown to exist. Discrepancies in much of the literature data can be explained on this basis. The data on vaporization of water from rippling films have been correlated. The data on non‐rippling films were correlated when the gas Reynolds number was calculated relative to the water surface.
