Warren and DuBois (1964) have proposed a modification of the Theoretical Hydraulic Principle and the Hydrokinetic Equation for use in predicting velopharyngeal orifice area. In the study reported here, the equation was subjected to further controlled model experimentation. The results of this experiment indicate that, given the pressure differential across the orifice and the rate of airflow through the orifice, the area of the orifice can be predicted with considerable accuracy, thus strongly supporting the use of the Hydrokinetic Equation for predicting velopharyngeal orifice area.
