多年来，人们一直在研究管道连接中的能量损失。水头损失系数(K)通常用于表征弯头、T形三通、四通、阀门和其他管件的损失。当使用精确的K值时，可以计算管网中任何位置的流量和相应的总水头。虽然K对于大多数管道接头和管件都有很好的定义，但文献中对十字路口的K的记录却很有限。这项研究是为了确定具有相同管径和不同流动组合的管道交叉中各种流动组合的K。本研究提供并创新性地提出了1000多个K的实验值，用于设计和分析等径管道交叉。
Energy losses occurring in pipe junctions have been studied for many years. Head loss coefficients (K) are commonly used to characterize losses across elbows, tees, crosses, valves, and other pipe fittings. When accurate values of K are used, the flow rate and corresponding total head at any location in a pipe network can be calculated. While K is well defined for most pipe junctions and fittings, the literature has limited documentations of K for crosses. This study was commissioned to determine K for a wide range of flow combinations in a pipe cross with equal diameter pipes and varied flow combinations. This study provides and innovatively presents over 1,000 experimental values of K for designing and analyzing equal diameter pipe crosses.
