Abstract: | We present contributions to the definition and hydro-energetically optimization of the single-phase and constant density fluids transport in a non-adiabatic stationary flow regime by pressurized, long and smooth pipes (non-finned). On define relevant energetically indicators thus the energetically efficiency of the transport, the energetically slope, the heat transfer efficiency, possibilities of the economical design based on the minimization of the total power lost by transport. The design is generalized using the hydraulic radius, economical section area and particularized for cylindrical pipes. The study highlights the influence factors, optimization measures that can be adopted in the design and exploitation. Finally, the study is exemplified by numerical calculus for two categories. |
