CAD for large scale pipe networks employed in land irrigation

In this paper a CAD code is presented for the design of pipe networks employed in the irrigation and reclamation of agricultural desert land. The program can be used for both design and simulation purposes, and allows the matching of the pipe network characteristics with the pump's characteristics. It incorporates a highly efficient, specially developed numerical solution procedure to solve the mathematical model equations. The code is employed in the design of a representative network and the results are displayed and discussed.
