| Abstract: | Bassed on the fluid motion equation, a method of the water pressure prediction in bottom liner slurry pipeline has been yielded,The average gradient ray length is used instead of non-circular pipe hydaulic diameter, the experimental results in 76mm pipeline system are consistent with the predicting values. |
