Hydraulic Radius of a Triangular Channel
Hydraulic radius, abbreviated as \(r_h\), is the area cross-section of water in a pipe or channel divided by the wetting perimeter.
Hydraulic Radius of a Triangular Channel formulas
\(\large{ r_h = \frac { A_c } { P } }\) | |
\(\large{ r_h = \frac { z\;h^2 } { 2\;h \; \sqrt {1 \;+\; z^2 } } }\) |
Where:
\(\large{ r_h }\) = hydraulic radius
\(\large{ A_c }\) = area cross-section of flow
\(\large{ b }\) = bottom width of fluid
\(\large{ h }\) = depth of fluid
\(\large{ w }\) = top width of fluid
\(\large{ P }\) = wetted perimeter
\(\large{ z }\) = width of channel slope
