COST ANALYSIS FOR SPRINKLER IRRIGATION SYSTEM

The paper, herein, presents a cost analysis for sprinkler irrigation system. Several alternative layouts for a square cultivated area up to 150 Feddan are presented. Friction head loss analysis is performed for each layout. Comparison is done to show the layout which has a minimum friction head loss. Also, cost analysis of pipeline system is performed to show the layout which has a least capital pipeline cost. A simple relationship is presented to estimate the total friction head loss of the proposed layout. Another simple relationship is presented to estimate the capital pipeline cost of the proposed layout. Both relationships are function of the side length of a square cultivated area, pump discharge, and several coefficients derived from basic equations of continuity and head loss
