Knowledge of entraining air physical mechanisms is yet not very extended, due to the many parameters involved and their complex interactions. Consequently, every also little deepening of tha matter can contribute to give little but important aids to the construction of a comprehensive theory of the phenomenon. In this paper either a theory or experimental data are presented that refer to big plants in which many parameters can be avoided: viscosity and surface tension of the liquid, turbulence generated by the nozzle, nozzle geometry, bubble presence in falling water. Theoretical and experimental data agree satisfactorily

Abstract
Knowledge of entraining air physical mechanisms is yet not very extended, due to the many parameters involved and their complex interactions. Consequently, every also little deepening of tha matter can contribute to give little but important aids to the construction of a comprehensive theory of the phenomenon. In this paper either a theory or experimental data are presented that refer to big plants in which many parameters can be avoided: viscosity and surface tension of the liquid, turbulence generated by the nozzle, nozzle geometry, bubble presence in falling water.
