To Tthe question on calculating hydrodynamic non-stationary currents and optimization of processes with them connected
Engineering Education # 10, October 2009
In work the analysis of some results received for today on non-stationary currents in channels is resulted. The form of a curve of acceleration of a stream is found optimum from a point of hydrodynamic resistance. The analytical decision of the equation of Prandtlja for friction factor is given.
