摘要
介绍了各国流量计算公式中摩阻系数的含义 ,探讨了实用流量计算公式中传送系数和雷诺系数的关系 ,对美国和前苏联的计算公式进行了计算比较 ,提出了燃气管道水力计算公式中相对粗糙度及临界雷诺系数的取值等注意事项。
The results of comparisons between different factors in practical gas flow equations are shown in this paper. The friction factors used in the code of China for design of city gas engineering are more great than friction factors in U.S.A. The value of wall roughness used in above mentioned code also more great than that in U.S.A. This case must be revised further.
