An analysis of air-water frictional pressure drop data for horizontal ducts was made. For small diameter, circular tubes and narrow rectangular channels, it is established that the frictional pressure deep profiles with increasing mixture quality (or superficial gas velocity) are characterized by critical values for gas Reynolds number, quality and friction factor. These characteristic features are in evidence for tests in which the total mass flux of the mixture is held fixed with increasing quality or superficial gas velocity. The effects of duct geometry and total mass flux on the critical parameters are documented and discussed. The results for two-phase flow friction factors are also presented. 18 refs., 7 figs., 1 tab.
