- Knowledge of the rheological characteristics of a mixture enables the defining of hydraulic losses in horizontal pipelines on the basis of dimensionless criterion type λ (Re gen), where λ is the pipe resistance dimensionless coefficient from the Darcy-Weisbach formula and Re gen is the generalized Reynolds number for the adopted rheological model. In order to describe the rheological character of plastic and viscous mixtures, the 3-parameter generalized Herschel-Bulkley model was applied. The complete gener-alized Reynolds number ReH for the Herschel-Bulkley model was formulated. The estimation of relative error ReH value determination for the laminar flow was conducted for two cases: when the yield point λ0 is taken into account and when it is not considered.
