Gas hold‐up was measured in a 2.54 cm diameter reciprocating plate column for countercurrent flow of air and tap water. The gas hold‐up data obtained could not be correlated by the relationship based on slip velocity, modified for circulation effects, as proposed by Rama Rao and coworkers. An analysis using other gas hold‐up data available in the literature, obtained in reciprocating plate columns of different sizes and geometries, confirmed that this relationship could not be used for the general prediction of gas hold‐up in this type of gas‐liquid contactor.
