摘要
文章论述了国内外输气管道绝对当量粗糙度的取值,并分析了管道绝对当量粗糙度的取值对管道的摩阻系数、压降、输送距离及最大输气量的影响。
The article discusses the values of the domestic and international absolute equivalent roughness of gas pipelines, and analyzed the influence of absolute equivalent roughness on the pipeline friction coefficient, pressure drop, transmission distance and the largest gas transmission capacity.
