Hydraulic Diameter - Engineering ToolBox

Hydraulic Diameter of Rectangular Tubes or Ducts. Based on equation (1) the hydraulic diameter of a rectangular duct or pipe can be calculated as., d h = 4 a b / (2 (a, +, b)), = 2 a b / (a + b) (4) where. a = width/height of the duct (m, ft) b = height/width of the duct (m, ft) Related Mobile Apps from The EngineeringToolBox

Equivalent diameter is not the same as hydraulic diameter.
