摘要
以一支L型皮托管的系数校准实验为例,分析了在风速计量中使用CIPM-2007公式计算空气密度的方法,评定了其不确定度,并将其与气态方程导出公式进行了比较。根据比较结果,建议在风速计量中使用CIPM-2007公式计算空气密度。
The paper takes the calibration of a L Pitot-tube for example, Experimental Investigation was carried out to evaluate CIPM-2007 formula for air density in the air velocity measuring, estimate its uncertainty and compare it with the formula derived from the equation of state of ideal gas. According to the comparison results, it is suggested that the CIPM-2007 formula should be used in the measuring of air density.
