Hydraulic Depth

on . Posted in Fluid Dynamics

hydraulic depthHydraulic depth, abbreviated as \(d_h\), also called hydraulic mean depth, is the area cross-section of water in a pipe or channel divided by the wetting perimeter.


Hydraulic Depth formula

\(\large{ d_h =  \frac  {  A_c }  { w }   }\) 
Symbol English Metric
\(\large{ d_h }\) = hydraulic depth \(\large{ ft }\) \(\large{ m }\)
\(\large{ A_c }\) = area cross-section of flow \(\large{ ft^2 }\) \(\large{ m^2 }\)
\(\large{ w }\) = fluid top width \(\large{ ft }\) \(\large{ m }\)
