A generalized method, based on the frictional law of corresponding states, is proposed for the correlation of two-phase flow frictional pressure drop data. It is validated using air-water data obtained on narrow rectangular channels and a circular tube for valves of total mass flux (G) in the 50--2000 kg/m{sup 2}s range. As with single phase flow, the results indicate that two-phase pressure drop for air- water mixture can be predicted from the proposed correlations provided the critical parameters are known. The fact that the critical parameters are observed to occur for values of quality (x) less than 0.01 for 50 {le} G {le} 2000 kg/m{sup 2}s makes it clear that pressure drop data for the x < 0.01 range are needed in order to apply the proposed method, just as laminar flow data are needed for the single phase counterpart. 4 refs., 8 figs.
