Verification of IRRILAB Software Application for the Hydraulic Design of a Micro-Irrigation System by Using IRRIPRO for an Apple Farm in Sicily

2021

In recent years, many studies have been performed to develop simple and accurate methods to design micro-irrigation systems. However, most of these studies are based on numerical solutions that require a high number of iterations and attempts, without ensuring to maximize water use efficiency and energy-saving. Recently, the IRRILAB software, which is based on an analytical approach to optimally design rectangular micro-irrigation units, has been developed, providing the solution corresponding to the maximum energy-saving condition, for any slope of the laterals and of the manifold. One IRRILAB limitation is that, according to its theoretical basis, the rectangular planform geometry and uni…

Minor Losses and Best Manifold Position in the Optimal Design of Paired Sloped Drip Laterals

2018

Arranging paired laterals so that two distribution pipes extend in opposite directions from a common manifold contributes to providing more uniform pressure to all laterals in the system, increasing water use and energy efficiency of micro-irrigation. Towards this end, by neglecting emitters’ minor losses, analytical procedures to design paired drip laterals laid on uniform slopes were introduced. More recently, it was shown that for an optimal paired sloped lateral design the best position of the manifold (BMP) equals 24%. In this paper, first the mentioned analytical procedure is extended to the case in which minor losses are considered. Second, by neglecting minor losses, a comparison in…
