Manufacturing Variation and Drip Irrigation Uniformity

Abstract

ABSTRACT THE coefficient of variation was used to assess the magnitude of emitter flow variation along single chamber drip irrigation lateral lines. The relationship between hydraulic variation and manufacturing varia-tion was found to be orthogonal. This independent rela-tionship allows the statistical combination of their respective coefficients of variation. As a result the statistical uniformity coefficient was recommended for use in determining the drip irrigation lateral line design uniformity including manufacturing variation.
