    Abstract

    The scope of this work is the definition of a leakage law in pipes to elastic behavior. The study uses the dimensional analysis method to describe the phenomenon of loss for elastic behavior pipes. The application of the theorem Π defines the dimensionless variables of the model of loss. The leakage equation is the result of the EPR (Evolutionary Polynomial Regression) method applied to laboratory experimental data. The subsequent comparison of leakage equation with the experimental data show a good agreement for both materials characterized by a high elastic modulus such as steel and for materials with a low elastic modulus such as uPVC. The study shows that the Torricelli equation is accurate only for rigid materials. The leakage equation is in good agreement with the Torricelli equation with variable area (May, 1994).
