顺序输送串联管路混油长度计算方法

METHOD TO CALCULATE THE INTERFACE LENGTH IN SERIES SEQUENCE TRANSPORTATION PIPELINE

运用等管径条件下的油品顺序输送混油长度计算公式,依据混油等容积原理,推导出顺序输送串联管路 (即不同管径)逐次符合上一段管径条件下的管路当量长度,进而得到整个管路的混油长度的计算公式。

By using the formula to calculate the interface length in series sequence transportation pipeline under equal pipe diameter, the equivalent pipeline length of series sequence transportation pipeline （ different pipe diameters） which accords with the diameter of the upper pipeline section by section is derived based on the interface principle of equivalent volume and, then the formula to calculate the interface length in whole pipeline is obtained.
