metadata.value: Lots of technical devices use ﬂows in pipes and channels caused by pressure drop, along with one’s axis, which is energy consuming and has to be estimated. For the estimation resistant coeﬃcient, dependent on ﬂow regime and streamlined surface roughness, is required. Turbulence f -model applicable for calculation for both laminar and turbulent ﬂow and smooth and rough walls is used for investigation. The problem of incompressible viscous liquid steady ﬂow in a smooth round pipe is considered for diﬀerent Reynolds numbers. First integrals for velocity proﬁle and turbulence measure are obtained in form of transcendental equations and solved by Newton’s method for algebraic equation system. Calculated results are compared with data from alternative theoretical approaches and experiments.
