Hydraulic calculation of pressure pipes

M.A. Mikhalev, Saint-Petersburg State Polytechnical University, Russia

In the present time there is only one classic method for hydraulic calculation of pressure pipes. In it fluid flow velocity and pipeline diameter are considered as given values.

The paper proposes a procedure for physical modeling and hydraulic calculation of pressure pipes, based on the theory of similarity.

Methods for obtaining similarity criteria from combinations of similarity numbers were discussed. Similarity numbers and criteria and criteria equations were defined.

Key words:

pressure pipes; hydraulic calculation; physical modeling; numbers of similarity; criteria of similarity; combinations of numbers of similarity; criteria equations; laws of resistance
