Jump to: navigation, search. The hydraulic diameter, DH, is a commonly used term when handling flow in non-circular tubes and channels. Using this term, one can calculate many things in the same way as for a round tube. It is defined as. D H = 4 A P, Hydraulic Diameter - an overview | ScienceDirect Topics

The hydraulic diameter is four times the flow area divided by the duct perimeter. The formulas given before show the diameter d. For rectangular and oval ducts a corrected hydraulic diameter should be used. (9.143)dh = 4A P, Hydraulic diameter -- CFD-Wiki the free CFD reference

Hence, for circular pipes the hydraulic diameter is the same as the real diameter of the pipe. Rectangular tube. For a rectangular tube or hole with the width and the height the hydraulic diamter is: Coaxial circular tube. For a coaxial circular tube with an inner diameter and an outer diameter the hydraulic diameter is: 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 is necessary. equivalent diameters hydraulic Dh and iso-kinetic Diso ...

To calculate the pressure loss of a linear conduit of rectangular or oblong cross section: When the specification imposes on us the speed: DH is used (hydraulic diameter). Ex:A fluid flows 2 m/sec in a rectangular duct 200 x 100, the pressure drop is calculated as for a pipe diameter 133 by selecting in the tab major head loss, "I prefer to enter the speed", and entering speed 2 m/sec . De is used (equivalent … Hydraulic diameter - OilfieldWiki

Hydraulic Diameter - A Field Perspective on Engineering ...

In other words, a 12 inch round duct or pipe has a hydraulic diameter of 12 inches. 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.
