Abstract
It is shown that if a moving electrodynamic force is distributed nonhomogeneously over the cross section of a channel, the pressure developing with turbulent flow must be determined by solution of the problem of the internal hydraulics of the channel. The possibility of such a solution is demonstrated with large values of the local slips. An analysis is made of the differences between the p(Q) characteristics obtained from the generally accepted characteristics. It is noted that the local velocities may strongly exceed the mean mass flow rate.
