Hydraulic Radius of a Rectangular Channel

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

hydraulic radius of a rectangle 2Hydraulic radius ( \(r_h\) ) is the cross section area of water in a pipe or channel divided by the wetting perimeter.

Hydraulic Radius of a Rectangular Channel formula

\(\large{ r_h =  \frac  {  w h }  { w + 2h }   }\)         

Where:

\(\large{ r_h }\) = hydraulic radius

\(\large{ h }\) = depth of fluid

\(\large{ w }\) = width of fluid
