THE HYDRAULICS STUDY OF THE PRESENT AND FUTURE SYSTEM FOR THE LIBYAN MAN-MAD RIVER PROJECT

Abstract

In this paper, we have studied the first phase of the river project (SARIR-SIRT/TAZERBOBENGHAZI) system, and the effect of connecting a new phase (KUFRA-Tazerbo) to the first phase. We studies the characteristics of hydraulic for instance overall losses in the pipes and the effect of roughness increase in the pipe, and acknowledging the pressures which the system exposed to, and comparing the hydraulic characteristics for the current state with the future state due to increasing in discharge, velocity and head losses. Then study the available alternatives such as add pump station and changing the type of pipes and their impact on the system. We have to utilize the (Applied Flow Technology) in analyzing and evaluating the process of the hydraulic system. It was found that the hydraulic system will be converted from free system to pressure system under pumping with pump station, and the pressure inside the pipes not exceed the allowable pressure with using the maximum discharge. Also it was found that using pipes (GRP) is more practical than pipes (PCCP), and using pipes (GRP) with diameter 3.25 m give the same efficiency of pipes (PCCP) with diameter 4.0 m.
