✦ Synopsis

Ah&act-Bubble

formation under constant pressure conditions has been investigated for wide range of variation of liquid properties.

Air bubbles were formed from single horizontal orifices submerged in liquids whose viscosity varied from 1-O to 600 cPs and surface tension from 37 to 72 dyn/cm. Air flow rate was varied from 2 to 250 cmslsec and the orifice diameter from O-0515 to O-4050 cm.

A model of bubble formation based on the concepts given by Kumar and Kuloor (for constant flow conditions) has been developed for the situation of constant pressure conditions. A good agreement between the theorv and the exoerimental data has been obtained over the range of variables mentioned above. _

Bubble formation from porous discs submerged in liquids of different physical properties has been investigated. It is found that the number of sites effective for bubble formation is much smaller than the total potentially available sites. The number of effective sites is found to be a function of t
