| Abstract: | The finite element method (FEM) was used to analyze hydraulic balance mathematic model for water supply network of automatic sprinkling system,the unit matrix equation of each section's hydraulic balance was aggregated into full matrix equation of network hydraulic balance.The network hydraulic condition was obtained by introducing the boundary condition of node pressure,solving the full matrix equation,automatic choice of diameter,and iterative calculation of nozzle's flow rate.The hydraulic balance calculation was achieved in a quick and accurate way by giving programmed algorithm procedure and case based operation. |
| Keywords: | automatic sprinkling water distribution network FEM hydraulic calculation |
