An apparatus, system and method for emulsifying oil and water, such as for emulsifying a sizing agent for use in treating paper or paperboard, introduces a continuous phase under pressure through a continuous phase nozzle of a venturi apparatus and into a mixing section. A dispersed phase is introduced optionally under pressure into the mixing section of the venturi apparatus. The emulsion formed in the mixing section is directed through a mixed phase nozzle and out of the venturi apparatus. The mixed phase nozzle diameter of the venturi apparatus is larger than the continuous phase nozzle diameter at a ratio of greater than 1:1 and less than 4:1.
