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