Abstract: The paper considers homogeneous condensation of water vapors of moist air in the atmosphere taking place during generation of clouds and mists. A method for calculation of a radius of water droplet generated and parameters of liquid inside is proposed. Peculiarities of homogeneous condensation taking place on centers with electric discharges are investigated. It is shown that the electric discharge leads to the electric pressure establishment at the droplet border and thus to the change in droplet radius as well as the pressure inside it.

Keywords: droplet radius, Laplace pressure, surface tension, heat and mass transfer during condensation, droplet on a charged center.
