【Abstract】 During the stage of the optimization of flow distributions, the constrained minimum of the concave function f(q) is found by the reduced gradient method. A global minimum may be obtained by successive computations. Base upon optimized head loss h, optimal diameters are found readily. The constraint of the standard diameter is satisfied by intruducing the limiting economical discharge. This optimizing technique can be applied to networks with the boasting pumping station in the pipe line and networks with storage reservoirs or elevated tanks.更多还原
