in initial flow distribution, make use of method of the minimum square summation, taking into account the length of pipe 在初分流量部分,采用最小平方和方法,并考虑管长因素。
using the method of the minimum square summation, counting larger index of pipe length, distribute initiatory flow of pipe networks . it can better considerate the pipe lenth's influence to flow, and it's results are fitter for the theories of flow distribution . it is the best one in all optimal methods and propitious to finish the calculation by computer 这种计高幂次管长的最小平方和法分配管网初始流量,既不要预先确定管段水流方向又特别加重考虑了管长的因素,是现有的流量分配方法中最可取的一种,还便于用计算机一并完成全部计算。
