• When air streams into a liquid flowing upward in a vertical small tube, two kinds of pressure drops occur ; that is, one is the pressure drop along the liquid stream line, and the other is that along the air stream line. After consideration of void fraction, a non-dimensional basic equation is obtained, using a simple model of confluence. For each flow pattern, semi-empirical equations of the former kind of pressure drops are obtained. An empirical equation which covers the whole region of flow pattern is obtained from these equations. An empirical equation of the latter kind of pressure drop which covers the whole region is also obtained.
