On the basis of the solution of the equation of the movement (in conception of «vortex backfill”) offered earlier, the generalized formula for a profile of speed of a turbulent and laminar current in pipes is received. The formula has binomial power shape. The received solution allows to consider speed of a turbulent kernel of a stream, or, more precisely, averaged on time value of axial component of this speed, as the sum of three items - carrying, parabolic and power but not parabolic. It is shown that the profile of turbulent speed of the basic part of a stream is described by the parabolic component. Transformation of the equation of movement in which solutions both laminar, and turbulent profiles of speeds (in the basic part of a stream) are direct lines (or very close to them) is offered. Some features of turbulent flow, similar to currents in a granular layer are noted.
