摘要
对聚氨酯内衬球墨铸铁管不同流速下的流量、压强差进行检测,并依据公式分别计算出此种管道的当量粗糙度k、海曾-威廉系数Ch、曼宁糙率系数n值,这些值可以为工程设计提供可靠依据和参考。
The flow rate and pressure difference of ductile iron pipe with polyurethane lining were measured under different velocities. Equivalent roughness k, Hazen-Williams factor Ch and Manning＇ s roughness coefficient n of the ductile iron pipe were calculated respectively according to the formula. The objective is to provide reference for the engineering design.
