There are several models for hydraulic designs and optimization of lateral lines depending on the existing pressure head profile flow which allows designing longer lines, therefore decreasing cost system implementation. A model has been developed to calculate required rate at inlet line using back step method. set equations was implemented in an algorithm R language. For calculations, following variables must be provided: end (Hend), coefficients K x characteristic equation (flow-pressure)...
