Significance of uniformity coefficient
WebCoefficient of uniformity, Cu and the coefficient of curvature, Cc, are the parameters based on D-size to define grading. Coefficient of uniformity, and coefficient of curvature, Where D. Cu = D 60 / D 10. Cc= (D 30) 2 /D 10 ×D 60. Where, D 10 — Particle diameter at which 10% of the soil mass is finer than this size. WebSep 6, 2024 · The pivot with the fair coefficient of uniformity (80 to 85 percent) corresponded to center pivot irrigation system number 4, case 1 (CUH = 80), a 12-year-old pivot. The uniformity of water application test indicated significant under-application of water on the outer spans of the pivot (figure 3).
