Experimental two-phase pressure drop data were obtained from a 1/4 x 2 x 60-in. vertical, uniformly heated, test section. The local volume fraction of steam was measured simultaneously with the pressure drop, thus allowing separation of the terms for hydrostatic and acceleration pressure drops from the over-all static pressure drop. The results are expressed in terms of an averge two-phase friction factor multiplier, R = DELTA P/sub TPF// DELTA P/sub L/O/sub ,/ and are co mpared with the Martinelli-Nelson correlation, the LottesFlinn correlation, and a correlation combining that of Martinelli-Nelson and a flowrate parameter. The ranges of variables include: pressure from 150 to 600 pstg; power density from 17.2 to 94.5 kw/liter of coolant; sub-cooling from 4.8 to 25.7 deg F; exit qualities from 0.009 to 0.065; exit steam volume fraction from 0.19 to 0.77; and velocities from 2.56 to 3.43 fps.
