【摘要】 在圆形断面的排水管道设计中，有时需要计算不满流条件下一定充满度时的流量及流速．针对有不满流的流量、流速与对应的满流的流量、流速的比值，现推荐的解析表达式，便于从充满度直接计算流量比、流速比更多还原

【Abstract】 In the design of drainage pipeline with circular section, flow and current velocity of certain full level on the unfull condition are sometime needed to be calculated. The ratios of flow and current velocity of unfull current to those of full current are needed here. The analytical expression recommended in this paper is convenient to calculate ratios of flow and current velocity directly from full level.更多还原
