Abstract
To create an optimum water conveyance and distribution system in the planning and design of a pipeline, it is necessary to choose a pipe diameter that satisfies geographical and hydrological binding conditions, yet is economical. Optimum performance throughout the entire pipeline system including key water facilities such as pressure regulating facilities and pump stations is another major consideration. For this purpose, we introduce some examples of trial calculations where the Cost Potential Method, the Linear Programming Method, and the Dynamic Programming Method were applied to a gravity flow pipeline that has no intermediary water facility. In addition, we suggest a method of handling facilities as dummy pipelines. We also introduce some examples of calculations for optimizing pipe diameters by applying the Linear Programming Method to a semi-closed pipeline having pressure regulating facilities and a pump-assisted gravity-flow pipeline having intermediary pumping stations.
