This paper further explores the physics of water condensation, using an experimental structure designed for that purpose. The data show a highly significant correlation (R2 >0.94, p value <0.001) between observed airflows and partial pressure changes from condensation, when the results of different experiments are pooled. Changes in air density on cooling provide insufficient energy to account for the airflow. The finding is that the kinetic energy of the chilled air falls short by an order of magnitude, even to move a relatively small proportion of the 20 kg of air contained within the structure. Meanwhile the physics of condensation indicate a surplus of kinetic energy is made available from the air surrounding the locus of condensation. At low rates of condensation a considerable proportion of the available kinetic energy in the enclosed air is absorbed in friction and turbulence. That proportion reduces with higher rates of condensation.

Este artículo explora la física de la condensación de vapor de agua bajo condiciones atmosféricas livianas, utilizando una estructura experimental diseñada para tal fin. Los datos demuestran una correlación altamente significativa (R2 >0.94, p valor <0.001) entre los flujos de aire observados y los cambios en la presión parcial resultante de la condensación, cuando los resultados de diferentes experimentos son unificados. Mientras la energía cinética del aire enfriado no tiene el nivel necesario para mover siquiera una fracción de la cantidad de aire, 20 kg, encerrada en la estructura, los principios físicos indican que un exceso de energía cinética disponible se deriva del aire que esta alrededor del punto de condensación. A una tasa baja de condensación, una proporción considerable de la energía cinética disponible se encontrará absorbida en fricción y turbulencia. Esa proporción se reduce cuanto mayor sea la tasa de condensación.
