DESIGN OF MULTISTAGE PUMPING MAIN

Pumping mains transport materials long distances. Pipelines transporting fluids against gravity and frictional resistance require multistage pumping. Equations for the optimal diameter and the pumping head for a single-stage pumping main are available. For multistage pumping, though, the optimal number of pumping stages are determined by an enumeration procedure. Such a process, though, does not show the functional dependence of input parameters on the design variables. This paper treats the multistage pumping main design as a geometric programming problem having a single degree of difficulty. The constant friction factor case of the problem yields a closed-form solution for a long pipeline with relatively flat topography. The variation of the friction factor with diameter is accounted for iteratively.
