This work intend an original methodology, newly established by the authors, to design typical pipe systems by using hydraulic criteria equations, excluding the determination of the relevant Darcy factor. Therefore, it can be eliminated the necessity for searching iterative solutions of such problems. The established equations are easy to use, in terms of mathematical processing, which guarantees their proper application in solving engineering problems. It is considered for the proposed physical relations (equations) concerning the determination of the pipe system resistance characteristics to be highly useful in engineering practice, as for example: in determining a hydraulic machine work regime, used in a system transporting fluids, as well as in performing a synthesis and analysis of such systems or in accomplishing an energy analysis of pipe systems. A comparative analysis between the results found after applying the classical methods of calculations and by using a licensed specialized software product indicates that a highly sufficient (for engineering calculations) overlapping is achieved.
