UPVC给水管沿程阻力系数的研究

Study of the Friction Factor of UPVC Water-pipe

通过对国产 UPVC给水管进行系统实验 ,对实验资料进行回归分析并与现有计算公式相比较 ,导出 UPVC给水管沿程阻力系数的计算公式 ,为

There are three calculating formulas of the friction factor of UPVC water pipe,but its results are too far apart.The calculating formula of the friction factor of UPVC water pipe is developed by systematic experiment of UPVC water pipe made in our country and carrying out regression analysis using experiment material and comparing with current fomulas,which provides bases for the head loss caculation of UPVC pipe.
