《油气储运》杂志1987年第2期刊登了李相怡、翁尔基两同志的“计算机预测减阻剂减阻率及其应用”一文,文中介绍了一个“LBD”程序,利用该程序可输出三种增输方案:①采用铺设副线法,给出应铺副线长度;②采用提高管压法,给出应增加的功率数;③采用加减阻剂的办法,则给出每天需加入的减阻剂量。 但是,该程序运行时。需输入由减阻剂及溶剂系统决定的四个经验常数A、B、C、D,原文没有
“Oil and Gas Storage and Transportation” magazine in 1987 second issue of Li Xiangyi, Orkji two comrades “drag reduction drag reduction rate of computer and its application,” a paper, the article describes a “LBD” program, the program can be output Three kinds of additional transport programs: ① laying pavement method, given the length of pavement should be sub-line; ② by increasing the pipe pressure method, given the number of power should be increased; ③ Addition and drag reduction method, given the daily needs The amount of drag reduction added. However, the program is running. Enter the four empirical constants determined by drag reducer and solvent system A, B, C, D
