The use of the Reynolds flux to assess momentum transfer and pressure drop behaviour in condensation was a basic idea of a paper by Silver (1)†. In the present paper the same concepts are used with more consistent logic to develop a simpler and more satisfactory treatment. Experimental results of velocity profile measurements show that the assumptions made are permissible. The predictions from the improved theory are generally in accord with those previously given by Silver (1) and now confirmed by Wallis in the first of these two papers.
