METHOD OF CONTROL OF PIPELINE CAPACITY Russian patent published in 2006 - IPC F17D1/16 F17D1/17 

FIELD: pipeline transport.

SUBSTANCE: method comprises determining new value of concentration of admixture θ_n from the equation for the coefficient of the hydraulic efficiency ψ(θ,Re ) = ψ₀(θ,Re_b)(1 - (2300/Re)^0.75)/(1 - (2300/Re_b)^0.75), where θ is the concentration of admixture, θ_n is the new value of the concentration, Re is the Reynolds number, and Re_b is the basic (initial) Reynolds number, by determining the Reynolds number (Re) for the changed fluid viscosity keeping the pipeline capacity constant and knowing the coefficient of the hydraulic efficiency for the base Re number and concentration for the constant capacity of the pipeline. The new flow rate of the anti-turbulent admixture is judged by the value of θ_n.

EFFECT: enhance efficiency.
