h = rQnEq. 1 a solution. Unfortunately, the a-c. network calculator relation between voltage and current, which are analogous to pressure and discharge, is a linear one, whereas the required relationship for water distribution is nonlinear. In order to compensate for this difficulty and to achieve acceptable results, a method of applying a correction factor to' the linear reading has been developed and is reported in this paper.The conventional method of solving hydraulic distribution system problems has involved the use of methods of successive approximations, such as the Hardy Cross system as modified by Doland (2-4). In such solutions, the relation between head loss, h, and discharge, Q, is:
