This thesis reports the results of temperature measurements made by thermocouples installed on the exterior surface of a single horizontal copper tube while saturated steam vapor was condensing within. Cooling was effected by cross flow of cooling water with one pass. It describes an experimental technique for making temperature measurements, The effect of vapor velocity on distorting the build up of the liquid film is shown. There is included a theoretical method for the prediction of local coefficients of heat transfer developed using the assumptions of the Nusselt theory. Overall coefficients of heat transfer were determined at two different steam conditions.
