By analyzing the momentum transfer and velocity both of solid particles and water over the acceleration time of solid particles, and interplay mechanism of water and solid particles, a new model is proposed to predict friction loss for setting slurry flow in inclined pipe. Based on the experimental data of some scholars, the hydraulic gradient formulas of the author and other inclined pipelines are verified. The results show that the deviation between the theoretical and measured values of the model proposed by the author is the smallest, not more than 13.33%. At last the causes of error is analysed.
