Determinação dos coeficientes de descarga (Cd) para vertedores retangular e triangular no IFSP – campus São Paulo
Abstract
This study aimed to determine the discharge coefficients (Cd) of rectangular and triangular weirs, through tests carried out in the didactic hydraulic channel of the Federal Institute of São Paulo – São Paulo Campus. The weirs, defined as hydraulic structures formed by a wall with an opening of specific geometry, arranged perpendicularly to the flow. They were analyzed based on the classic formulations of Francis and Thomson, disregarding the effects of viscosity, surface tension, wall roughness and upstream flow regime, which is why the discharge coefficient is used to compensate for these approximations and ensure greater representativeness of the real flow. For the treatment of experimental data, the Least Squares Method was applied, allowing the estimation of Cd values. The results obtained provide reference parameters for the calculation of flow rates and water depth, contributing to future academic and experimental applications.
