Effects of Wear of Pressure Regulating Valves From a Center Pivot Irrigation in Its Uniformity of Water Application and Optimum Depth of Bean Irrigation
Abstract:Considering the influence on performance of PRV's water application uniformity of center pivot irrigation systems, this study had the aim to compare, under simulated conditions of two distinct wear PRV's (new PRV and PRV with more than 8000h of use) the values of water application uniformity, optimum water application depth and optimum productivity of bean (Phaseolus vulgaris). Results showed that worn PRV causes a 5.1% reduction on center pivot water application uniformity coefficient value. After correcting … Show more
