            Abstract : 
Based on the assumption that flow pattern in tube settlers is laminar and the distribution of flow velocity is a circumgyratetional paraboloid, general hydraulic equations are deduced, with consideration of the effectors of acceleration a and initial fall velocity u0i of setting particles, and length li, counting radius ri, and obliquity of circular settling tubers. Comparison with other equations presented by other researchers indicates a good agreement. A deduced removal efficiency formula for tube settlers with consideration of particle distribution could be calculated by software of matlab.
