输气管道计算式相关系数的更正

Correction on Related Coefficient of Equations for Gas Transmission Pipelines

摘要: 介绍了目前世界上输气管道常用的5个计算公式, 即威莫斯公式、潘汉德尔A式、潘汉德尔B式、苏联天然气研究所早期公式、苏联天然气研究所近期公式。通过对5个输气管道计算公式的推导, 得出计算式中在P、L、D、Q采用国际单位制下的Ci值和P、L、D、Q采用相应单位时对应的Ci值, 并和文献1中给出的Ci值进行比较, 发现存在的差别, 通过新旧Ci值的对比, 对文献1中的Ci值进行了更正。

Abstract: The 5 equations (Weymouth, Panhandle A & B, and so on) commonly used in gas transmission pipelines are introduced. By derivation, a new C_i is obtained from these equations. And at the same time a comparison is made with the old C_i given in a works by LI Changjun (2000), and a difference is discovered by the authors. By comparison between the new C_i and old C_i, the correction to LI Changjun's C, is made.
