TO CALCULATION OF AVERAGED VELOCITY DISTRIBUTION IN ROUND PIPES AND FLAT CHANNELS

Authors:Vysotskiy Lev Ilich

Annotation

In the paper new analytical dependences describing the distribution of averaged velocities in longitudinal homogeneous flow validated for a wide range of the Reynolds number and the relative equivalent roughness. The methodology for calculation the dimensionless averaged velocities accompanies by explanations. To implement the input there are two key parameters, the Reynolds number and the relative equivalent roughness. In order to receive dimensional values the additional input of characteristic length L ( r – radius for round pipes, H – depth for flat flow) and dynamic velocity u , is required.
