Abstract
Objetivou-se, neste trabalho, modelar a perda de carga contínua, em tubulações comerciais de aço zincado, utilizados
na condução da água residuária de avicultura (ARA). A água residuária foi avaliada em seis concentrações de sólidos
totais (0,26; 0,46; 0,73; 0,94; 1,63 e 2,89 dag L -1 ), em tubulações comerciais de aço zincado, nos diâmetros comerciais
de 50 a 150 mm. De acordo com os resultados, verificou-se que as equações empíricas, ajustadas com a aplicação
das metodologias de Sampaio et al., Duffy & Titchener e Hazen-Williams modificada, apresentaram bons ajustes,
com coeficiente de correlação acima de 0,90, sendo recomendada sua aplicação no dimensionamento de sistemas de
bombeamento dessas águas residuárias.
This objective of this study was to model the continuous load loss in the commercial zinced steel pipes used in the management of wastewater from a poultry shed (WP). The WP was evaluated at six concentrations of the total solids of 0.26, 0.46, 0.73; 0.94, 1.63 or 2.89 dag L -1 was transported using commercial zinced steel pipes of 50 to 150 mm diameters. The empirical equations adjusted with the methodologies of Sampaio et al., Duffy & Titchener or modified Hazen-Williams gave good results, with correlation coefficient above 0.90 and its application is recommended to design projects.
