The bubble formation at the inclined orifices is investigated at the constant pressure system (constant pressure supply). It is found that the gas flow rates, the orifice dimensions, the chamber volumes and the physical properties of liquid affect the bubble volume. In the regions of the low gas flow rates and the small chamber volumes, the bubble volume increases with the inclination of the orifice with respect to the horizontal. The values of critical chamber number, up to which the bubble volume do not depend upon the gas flow rates and the chamber volumes is a function of the orifice diameter and the physical properties of liquid. By the application of Newton's second law of motion, the various forces acting on the surface of bubble are related. This model is examined by the experimental data, and the correlation with respect to the bubble volume is obtained.
