Hydraulic Radius of a Trapezoidal Channel (Equal Side Slopes)
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 Trapezoidal Channel (Equal Side Slopes) formula
\(\large{ r_h = \frac { h \; \left( b \;+\; z\; h \right) } { b \;+\; 2\;h \; \sqrt { 1 \;+\; z^2 } } }\) |
Where:
\(\large{ r_h }\) = hydraulic radius
\(\large{ b }\) = bottom width of fluid
\(\large{ h }\) = depth of fluid
\(\large{ z }\) = width of channel slope
