| 摘 要： | 在流体阻力测定实验中,确定直管摩系数时,对不同的实验装置,将流速与压差间的关系用线性回归法求得经验公式,以便用孔板流量计两端的压差读数Ｒ直接计算出流体的流速μ,可以简化实验和计算过程。

| Abstract: | The paper is intended to define the friction-coeffici ent of straight-tu be,and to establish a expecience formula by means of linear regress,so we can ca lculate the flow rate by difference of pressure directly,it makes the calculatio n and expdriment more simplify. |

| Keywords: | flow rate difference of pressure linear regre |
