Abstract:
Pipeline transportation of oil is considered to be one of the basic and cost-effective ways of their delivery to the place of
consumption. Moreover, in the case of using electricity, the higher the viscosity of the transported oil is, the more power
consumption is. For pipeline transport, it is characterized the movement of the oil in an isothermal mode, in which it
changes its rheological properties, moving from a Newtonian fluid at high temperatures of the transported flow to a non-
Newtonian one. In Russia, it has not been created a sufficiently rigorous theory of motion of highly viscous flows so far.
