Pressure drop measurements in a 15-row steam condenser configured with in-line tubes, p / D = 1.33, are described. Pressures from 50 to 100 mb and Re_max in the range 1,000- 18,000 were imposed. It is shown that pressure loss coefficients for the bundle and for two-row pairs wee lower than predictions for equivalent single-phase tests except near the bottom of the bundle. Three was some evidence that increase in suction parameter increased this effect in the top rows.
