The dependence of the height of capillary liquid retention on a horizontal finned cylinder on the interfin spacing is determined experimentally for water and Freon-12. New experimental data are obtained on heat transfer in film condensation of quiescent Freon-12 vapor on eleven finned cylinders. In the experiments the interfin spacing and the fin thickness varied within wide ranges. The feasibility of the weight of finned tubes being substantially reduced by a proper selection of the optimal geometric dimensions is established. The experimental data obtained are processed in dimensionless coordinates.
