Critical flow velocity is an important factor in slurry pipeline transportation. Now, there is not still an universal formula. 臨界流速是漿體管道輸送的一個重要因素，目前尚無普遍的使用公式。
The author also provided basic pressure drop equations for different flow regimes of bulk Solids and Slurry Pipeline Transportation design calculation procedures. 并給出了對于不同物料流動狀態(tài)的壓力損失計算公式及漿狀管道輸送的理論設(shè)計計算步驟。
Therefore, the study would help to develop long distance slurry pipeline transportation and accelerate the researches and developments of the solid-liquid two phases flows theory. 因此，進(jìn)行該理論的研究，有助于發(fā)展?jié){體物料的長距離管道輸送，且對固、液兩相流理論的研究和發(fā)展產(chǎn)生巨大的推動作用。
