THE ANALYSIS OF FORMULAS AND THE EXPENSE AVERAGE SPEED OF WATER
On the basis of reconstruction of data of V.F. Talmazy and G.N. Romanenko validity of application for calculation of average on section of a stream of speed of water in open natural waterways of the formula of O.S. Kopystjansko corrected by us and the parity received from the formula of G.N. Romanenko is established.
