Friction Head Loss in Center-Pivot Laterals with Single Diameter and Multidiameter

In this paper, efficient closed form expressions to compute the friction head loss in center-pivot laterals using the method of the discrete outflow distribution are presented. The results are applicable to center-pivot systems with single diameter and multidiameter, with constant spacing between sprinklers along the lateral, with and without end gun sprinklers, and with and without closed outlets at the beginning of the lateral. The head loss...
