| Abstract: | In view of the problems existing with the use of trial-calculation method and chart method in the hydraulic calculation of hydrant nozzles,an analytic equation which can be directly used in calculation is deduced through optimizing and fitting the original solving function,which can be easily applied by basic-level designers in practical engineering design.It is shown by the analysis of the calculation accuracy with the said analytic equation that within the range of normally-used parameters,the maximum fitting error is only1.49%,which satisfies the requirement in the current norms. |
