编制过程中,将原《全国通用通风管道计算表》中钢板风管、除尘风管、气密性风管的主要数据,经计算并测试校核后进行精简列入新编内容,同时增加了螺旋风管、水硬性无机玻璃钢风管、氯氧镁水泥风管、玻纤风管、酚醛风管、聚氨酯复合风管等的计算图表。误差分析表明,比摩阻的绝对误差为0.067Pa/m,相对误差为2.54%。 During the compilation process, the main data of the steel pipe, the dust pipe and the air-tight air pipe in the original “National General Ventilation Pipeline Calculation Table” were compiled and tested. Spiral duct, hydraulic FRP duct, magnesium oxychloride cement duct, fiberglass duct, phenolic duct, polyurethane composite duct and other calculation charts. Error analysis shows that the absolute error of specific friction is 0.067Pa / m and the relative error is 2.54%.
