Hydraulic Diameter
Hydraulic diameter, abbreviated as \(d_h\), is normally used when the flow is in non-circular pipe or tubes and channels. Circular pipe has the same pressure drop of a rectangular channel but a greater average velocity. Square or rectangular pipes have a greater weight and a greater pressure drop compared with a circular pipe with the same section. For established shapes, various calculations are linked below.

\(\large{ d_h }\) = hydraulic diameter | \(\large{ ft }\) | \(\large{ m }\) |
\(\large{ A_c }\) = area cross-section of flow | \(\large{ ft^2 }\) | \(\large{ m^2 }\) |
\(\large{ P }\) = wetting perimeter cross-section | \(\large{ ft }\) | \(\large{ m }\) |
