Hydraulic Radius
Hydraulic radius, abbreviated as \(r_h\), is the area cross-section of water in a pipe or channel divided by the wetting perimeter.

\(\large{ r_h }\) = hydraulic radius | \(\large{ ft }\) | \(\large{ m }\) |
\(\large{ A_c }\) = area cross-section of flow | \(\large{ ft^2 }\) | \(\large{ m^2 }\) |
\(\large{ P_w }\) = wetting perimeter | \(\large{ ft }\) | \(\large{ m }\) |
