Two-fluid model for description of flows in pipes of circle profile is presented. This model explains well-known experimental fact which consists of growth (approximately in 2 degrees) of critical Reynolds number at which transfer to turbulent regime takes place in comparison with pipes of other profiles. A special characteristic of this model is that a set of vortices arise which separate flow from walls of pipe. An electromagnetic analogy with infinitely long solenoid is used for determination of flows’ parameters.
