本文提出一种新的图解方法求解简单角联管网,根据hi=R_iG_i~2,ΣQ_i=0,Σh_i=0三个基本关系,不必求助于解多元二次方程和Q_i等计算,可直接用作图法求解. 文中着重说明该法的基本原理和作图方法步骤,并举例运用该法求解某一简单角联管网,将结果与A.C.波波夫近似计算法所得结果比较,以说明其精确程度.这种方法只能求解简单角联管网,从理论上看,它并无近似之处,因作图的误差使结果不能绝对精确,只要图作得精细,能比近似计算法更为精确些.
In this paper, we propose a new graphical method for solving simple corner pipe network. According to hi = R_iG_i ~ 2, ΣQ_i = 0, Σh_i = 0, we do not need to resort to the solution of multivariate quadratic equation and Q_i, This paper focuses on the basic principles of the law and the steps of the mapping method, and gives an example to use this method to solve a simple corner pipe network, and compares the results with those obtained by the AC-Popov approximation method to illustrate that Accuracy. This method can only solve the simple corner pipe network, in theory, it has no similarities, because the error of the drawing so that the result can not be absolutely accurate, as long as the map is fine, than the approximate calculation method more To be accurate.
