초록

In this study, the optimal analysis for pipe network is performed for the combined ideal pipe network system(CASE 1, CASE 2, CASE 3, CASE 4, CASE 5 and CASE 6) which is composed of 42 nodes, 72 elements, and 1 fixed nodal head with evaluating pressure variation distribution of main and branch and fluid analysis methods(EPA-NET model) in grid composed drainage pipe network. In the analysis of pipe network, the CASE 3 and CASE 5 supply same value in the result of considering the total flow provided each pipeline, but in the general intension in the case of CASE 1, 2, 4 and 6, relative width of supply is more large than CASE 3 and CASE 5. In the analysis technique of pipe network, CASE 3 is analysed largest as a result of comparing with same heads, and in the order of their size CASE 5, CASE 2, CASE 6, CASE 1 and CASE 4 were determined but the difference doesn't appear to be obvious. It is found that C-M method provides the small amount while H-W and D-W method provide the almost same amount from the result of the examination of the total supply distributed to each pipelines in the analysis of the distribution system. It is appeared that D-W, H-W and C-M method are arranged according to the size of pressure and Hydraulic grade level. In this study, discharge flow distribution is evaluated in the same condition with 3-type CASE in the case of branch position for designing optimal composed drainage pipe network. As the result of that, branch pipe perform. Therefore, it is thought that the efficient and reasonable management of water supply and sewerage design will be possible if it give all our energies to study at the pipe system design in and out of country in the future.
