Resumo

This study investigates the speed of pressure wave propagation in PVC pipelines, with a particular focus on analyzing the influence of each variable involved in wave speed calculation within an elastic model, as compared to a rigid model. The research determined experimentally the values for the elastic modulus. To ensure accurate material characterization, laboratory tensile tests were conducted to determine the actual elastic properties of the PVC pipes used in the analysis. Additionally, the study considers the influence of other parameters, including the water bulk modulus, density, and pipe diameter, which also contribute to the determination of wave speed, though to a lesser extent. The results demonstrate that variations in the elastic modulus of the pipe material have the most substantial impact on wave speed folowed by pipe anchoring coeficient, surpassing the effects of temperature and other geometric factors.
