A method is described for calculating drop sizes obtained in Newtonian immiscible liquid‐liquid systems when a dispersed fluid is continuously injected at uniform subjectting point velocities through a sharp‐edged nozzle that is preferentially wet by the continuous phase. This method is based on the calculation of the shape of a drop forming at the nozzle tip by means of a pressure balance over the drop interface and the use of a force balance to determine if any portion of the forming drop can break away. Calculated drop sizes are compared with experimental data for systems of different physical properties.
