Steam was condensed in a four inch inside diameter column packed with three‐eighth inch ceramic Raschig rings using Aroclor 1242 and 1248 as co‐current heat transfer agents. The packing heights used for condensing the steam were estimated from the liquid temperature profile in the column. From this value and the liquid temperatures the height of a transfer unit for condensation ( HCU ) was calculated. The HCU was found to be strongly affected by the mean heat transfer medium viscosity and by the flow rate of the liquid. Two empirical equations have been developed to describe the results of this study. Both are of the form\documentclass{article}\pagestyle{empty}\begin{document}$$ HCU = F\left( \mu \right)^n \,. $$\end{document}
