A technique for use in calculating the rational diameter of a pipeline by means of which the diameter of a pipe may be selected to achieve a minimally possible total cost of construction and operation of the pipeline in the case of a given flow rate of fluid assuming a designated period of operation is presented. The technique is constructed on the basis of two equations, an analytic equation of continuity of flow (Darcy−Weisbach equation) and equations for use in calculating the friction coefficient in rough tubes. The following parameters are taken into account here: the variation of the total cost of transporting the flow of fluid as a function of the diameter of the pipe with assigned volumetric flow rate of fluid, assigned period of operation of the pipeline, and the cost of a single linear meter of pipeline.
