Abstract:
Three pipelines with different diameters were studied in this thesis to transport gasoline and gasoil products from Haya station –which lies on Al-bahar Al-ahmer state – to meet needs for Gadaref and Kassala states in addition to Ethioupia .this study is done by using Google Earth software program to identify the alternatives for these line and identify the best route. Also pipesim software program is used to determine required line pressure and required number of pump stations for each line , and cost estimation was established for each line to select appropriate diameter for this line to transport the products with high quality and minimum cost. The results show the best alternative is 10 inch with two pump stations.
