Head Loss and Pressure Head in Central Pivots for Citrus Irrigation
Article Sidebar
Main Article Content
Abstract
Irrigation of citrus plantations contributes to obtaining profitable harvests and for this, central pivot machines are used, among other techniques. The equations for calculating head loss and pressure head, available for center pivots with full coverage irrigation, do not provide sufficiently accurate results on irrigation machines configured for citrus. The objective of the present study is to develop new mathematical expressions for the calculation of head loss and pressure head in central pivots configured for citrus irrigation. The equations of these two hydraulic parameters are presented, which guarantee sufficient precision, validated by field measurements.
