Abstract in Portuguese
O presente trabalho versa sobre o termo de atrito em escoamento transitório em condutos forçados, partindo de uma modelação matemática da tensão de cisalhamento transiente, usando conceitos do princípio da entropia máxima. Usa-se a modelação deste termo de atrito na análise do transitório hidráulico, comparando-se com dados experimentais já publicados de um sistema Reservatório-Tubo-Válvula.

Friction term for hydraulic transient in closed conduits.

Abstract in English
This report contains a friction term for hydraulic transient in closed conduits. We use a mathematical model for the shear stress, derived by principle of maximum entropy. Then, we use this friction term for an analysis in a system reservoir-tube-valve, comparing our results with anothers already published in the literature.
