The paper presents the results of a computational-experimental study and makes recommendations on the calculation of heat transfer and hydraulic resistance of saturated and superheated vapors of different liquids condensing in vertical tubes and coils. A procedure is suggested for generalizing the local heat transfer with the use of the film thickness as the determining linear dimension as well as providing a technique for generalizing the mean condensation heat transfer in tubes and coils. Single relations are obtained to calculate hydraulic resistances in wide ranges of geometrical and operational parameters.
