- Abstract:
-
The hydraulic calculation of automatic sprinkler system is relatively complex; some of which need to use professional software for calculation. However, with the implementation of the new version of Code for Design of Sprinkler Systems (GB 50084-2017), the hydraulic calculation method abandoned the Shevirev formula of old version of Code for Design of Sprinkler Systems (GB 50084-2001) and adopted the HazenWilliams formula, some of the original simple calculation methods could not be applied.Previous calculation methods always based on the most unfavorable point nozzle at the end of the pipe network, the pressure and flow rate of the system are calculated.The EXCEL iterative calculation can be used to calculate the flow rate of the nozzle and pipe section in any selected area according to the pressure value of the pipe system, and according to the calculation results, optimize the layout of the nozzle.
