Equivalent diameter is not the same as hydraulic diameter.

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)

Hydraulic diameter - en.LinkFang.org

Hydraulic diameter, is mainly used for calculations involving turbulent flow. Secondary flows can be observed in non-circular ,ducts, as a result of turbulent shear stress in the turbulent flow. ,Hydraulic diameter, is also used in calculation of heat transfer in internal-flow problems. List of ,hydraulic, …

Hydraulic Diameter - A Field Perspective on Engineering ...

Interestingly enough, a 12 inch square duct (one square foot) also has a hydraulic diameter of 12 inches. But, if you hold the cross-sectional area constant at one square foot and vary the aspect ratio, the hydraulic diameter starts to decrease as the aspect ratio the duct increases above 1.

Physics:Hydraulic diameter - HandWiki

The ,hydraulic diameter,, D H, ... Channel of water or partially filled ,rectangular, duct. Open from top by definition so that the wetted perimeter consists of the 3 sides of the duct (2 on the side and the base). ... ↑ ",Hydraulic Diameter, for Non-Circular ,Ducts,". May 2017. p. 2.

Hydraulic diameter - calculator - fx Solver

For shapes such as squares, rectangular or annular ducts where the height and width are comparable, the characteristical dimension for internal flow situations is taken to be the hydraulic diameter. The hydraulic diameter can be calculated by the cross-sectional area and the wetted perimeter of the ducts.

Equivalent diameters of rectangular and oval ducts - P ...

Thus the experimental work needs to be repeated to verify whether ,hydraulic diameter, may be used as an `,equivalent diameter,' or whether an alternative relationship can be found. Practical application: In showing that there are no reliable practical results to guide engineers in calculating pressure drop along non-circular ,ducts,, the paper demonstrates that further practical research …
