摘要

介绍圆管风速简易测量法的原理

并将这种方法和等面积圆环法的测量结果进行了比较。在管径D =40 0mm～ 2 2 0 0mm

气流温度T =0～ 40 0℃

气流最大速度umax=10m/s～ 45m/s范围内

编制程序计算了圆管内的平均流速

给出了现场常见的两种管径平均流速计算的线算图

Abstract

This paper introduces the principle of a method for velocity measurement in tubes and its comparison with the equal area method.A computer program is developed to calculate the mean velocity in tubes

which have an diameter D=400-2 200 mm

flow temperature T=0-400 ℃ and tube center velocity u max =10-45 m/s.Nomograms for two common adopted tubes are given for engineering application.
