| Abstract: | By combining the node economic equation and boundary head condition,the water supply network mathematical model of economy-technique calculation is made.By using Newton iterative method to calculate the node's economy head,every economic pipe diameter can be solved,and calculation frame is presented in the light of the known and unknown of starting point pressure water supply network.Based on designing general iterative program and actualty calculater example,this paper satisfied with the results quickly and exactly,in order to release the designers from the complexities of the approximate calculations. |
