1.
Though comparing and analyzing the hydraulic performance of varied new pipe for water supply, the author comes to the unit length head loss s ratio K between the new pipe of varied diameter and the zincification steel pipe of corresponding nominal diameter.
通过对各种新型给水管材之间水力工况的比较和分析 ,推得各种管径的新型给水管材与相应公称直径的镀锌钢管单位长度水头损失的比值K ,由于管材间水力工况的不同 ,在工程设计、施工中更换管材时 ,不能简单地用相同或相近管径的管材互相替代 ,而应重新对系统进行水力计算。
