摘　　要：本文根据试验结果,运用流体力学原理,研究了不同情况下几种长柄滤头的水头损失变化情况,提出了在单独水反冲洗、单独气反冲洗和气水同时反冲洗情况下,长柄滤头的水头损失计算方法。Based on the experimental results,with application of principles of fluid mechanics,this paper has analyzed the variation of head loss through air-water nozzles under different conditions. It has developed the method of calculation of head loss through nozzles during backwashing with air and water, either sequentially or simutaneouslly.
