Özet

The main function of drip irrigation is to meet consumptive water use requirements of a crop within certain hydraulic and uniformity conditions. In this study, a graphical method was evaluated for determining lateral and manifold pipe diameters to obtain water distribution with an acceptable uniformity in drip irrigation. It was suggested that pipe diameters should be selected when Christiansen's uniformity coefficient, C-u, was equal to or greater than 98 and 97.5 % for lateral and manifold pipelines, respectively. Design charts for which uniformity coefficients could be directly found were prepared for commonly used lateral and manifold pipe diameters. Copyright (c) 2005 John Wiley & Sons, Ltd.
