Submerged gas injecting bottom lance design parameters are modelled by applying the theory of compressible flow of gas under irreversible‐adiabatic conditions. Using the criterion of onsetting the jetting mode of injection of gas into liquid the lance design paramters such as upstream stagnation pressure and Mach number, length of the lance for a given diameter and material, gas injection rate etc. are determined. Nomograms are presented to determine the above mentioned lance design parameters. The derived parameters are discussed in relation to submerged gas injection practice.
