Bubble volumes formed at a single circular hole drilled in a pipe have been measured. The variables investigated are, gas flow rate, inclined angle of orifice, hole diameter, physical properties of liquids, and chamber volume. It is found experimentally that the bubble volume is affected by the inclined angle of orifice in the low gas flow rate region, and for the liquid of low viscosity under less than the critical value of the chamber number given by Tadaki et al. Furthermore, the analytical method presented in previous work has been applied to this region. The experimental values agree well with the analytical results. Also, this type of bubble formation is similar to that of the inclined flat plate orifice.
