| Abstract: | When fluid flows through the tube,its amount of outflowing 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 8]π in the formula of Poiseuille. |

| Keywords: | the analyses of dimension the formula of Poiseuille fluid amount of outflowing |
