摘要
Abstract
To evaluate the accuracy of four commonly used hydraulic formulas for gas transmission pipelines,two pipelines with different diameters were selected,and the calculated results from the four formulas were compared against the measured field data.The results show that:the basic flow rate formula has wide adapt-ability and high calculation accuracy,but its calcula-tion results are tend to be relatively conservative.The Panhandle A formula is suitable for pipelines below DN 500 mm and has high accuracy within a certain range.When this formula is used to calculate large-diameter pipelines,the deviation is relatively large,so it is not suitable as a hydraulic calculation formula for pipe-lines of DN 900 mm and above.The Panhandle B for-mula also has wide adaptability;it has high calculation accuracy for pipelines of DN 900 mm and above,but its accuracy is slightly lower than that of the Pan-handle A formula for pipelines below DN 500 mm.The hydraulic formula developed by the All-Union Scien-tific Research Institute of Natural Gas is relatively complex and involves numerous parameters;however,it offers high computational accuracy and possesses considerable practical value.关键词
