A formula for the heat transfer of the dropwise condensation on the vertical flat surface was presented by N. Fatica and D.L. Katz. But Calculated value of the heat transfer coefficient from the formula is very lower in comparision with the experimental value, as it excepts one important factor which may increase the heat transfer by the action of the natural falling droplets, that is, these droplets act to fall forcedly many other growing droplets on the surface. In this paper, the formula included this factor was found and mainly compared with the Fatica-Katz's experimental data.
