【摘要】 本文把我们提出的管内压头分布公式制成了诺漠图,从而把简化计算从上文的几个方形虑池的特例,推广到任意的方形和矩形滤池的普遍情况。本文还考虑了穿孔管孔口流量系数μ的沿程变化,并得出了计算流量系数μ的简化方法,这样就完善了计算方法,提高了计算精度,保证了配水的均匀性。而且给出了穿孔管配水系统均匀配水水力计算的算例。更多还原

【Abstract】 In this paper, we present some nomograms based on the formula we suggested in our former paper of pressure distribution in a pipe The. simplified calculation method suitable for only a few square filters mentioned in the former paper is made universally applicable to any square and rectangular filters. We have also taken account of the variaton of the flow coefficient(μ) along the pipe and have worked out the simplified method for calculation which increases the accuracy of calclation and ensures uniform distribution.更多还原
