明渠水流临界水深计算
Critical depth calculation for current in ditch
【摘要】 在明渠水力计算中,常需要计算临界水深,以判别水流流态。工程上常用试算、图解等方法求解,极不方便,且精度不高。文章推导较简捷的公式,对梯形、矩形和圆形断面,采用通用的计算程序,以期达到准确的计算结果。
【Abstract】 Critical water depth is usually calculated to distinct the state of water current. Repeated calculation and illustration are often used in engineering, but such methods are really inconvenient and imprecise. In this article, the authors want to deduce a brief formulation, and use all - purpose program to get exact result for echelon,rectangle and rotundity cross section.
