本文从无量纲化角度入手,运用量纲分析法,通过分析文丘里流量计实验流量公式中的无量纲,先定性分析μQ与哪些因素有关,再借助实验数据定量分析它们之间的关系。
Starting from dimensionless point of view, dimensional analysis method was used to analyze the relationship between μQ and qualitative factors by qualitative analysis of the dimensionless flow in Venturi flowmeter. Then, the relationship between μQ and experimental data was quantitatively analyzed.
