Abstract
This paper deals with a two-layer multiparameter algebraic model of st eady turbulent flow in a round pipe with sand roughness. The model is based on generalization of the three-parameter model of flow in a pipe with smooth walls [1]. The proposed model enables one to describe the variation of the resistance coefficient in the entire investigated ra nge of Reynolds numbers (Re > 10(6)) for the roughness parameter value s R/h > 126. For smaller values of this parameter (R/h < 126), only tr ansition (incomplete roughness) flows could be described.
