摘　　要：摩阻损失是浆体管道输送工程设计中的一个重要参数,而摩阻损失的确定又取决于摩阻系数的计算,因此工程设计时对摩阻系数计算公式的选择尤为重要。本文针对浆体紊流输送时常用的几个摩阻系数计算公式,通过计算进行对比分析,并进行总结,为浆体摩阻系数计算公式的选择提出建议,供设计参考。Friction loss is an important parameter in the design of slurry pipeline transportation engineering. Friction loss depends on the calculation of friction coefficient, so the selection of friction coefficient calculation formula is very important in the engineering design. In this paper several commonly used friction coefficient calculation formulas of slurry turbulent transportation were summarized and analyzed by calculation, and it provided suggestions and referenee for the selection of friction coefficient calculation formula and engineering design.
