摘要
流体在管道内流动时,其流量与管道的几何尺寸,流体性质,管道两端的压差有关,其规律即泊肃叶公式。本文采用量纲分析法推出泊肃叶公式的基本形式,再用实验来验证。确定式中的比例常数k与泊肃叶公式中的常量8π等值。
When fluid flows through the tube ,its amount of out flowing is concerned with the dimensions of the tube,the essence of the liquid and the pressure differential at both ends of the tube. This is what is known as the formula of Poiseuille. This article deduces the basic form of the formula of Poiseuille with the analysis of dimension, then verifes it by experiment and determines the ratio k in that form and the constant quality π/8 in the formula Of Poiseuille.
