| Abstract: | In order to improve the calculation accuracy of local resistance in hydraulic calculation of gas network, the equivalent length method is used to calculate the usual gas distribution pipeline sections. The proportion of local resistance to the resistance along the pipeline section is obtained. The recommended table for proportion of local resistance to the resistance along the pipeline section is given. |
