Hydraulic Radius of a Partially Full Pipe (Less than Half Full) formula

\(\large{ r_h =  \frac  {  A_c }  { P_w }   }\) 

Where:

 Units English Metric
\(\large{ r_h }\) = hydraulic radius \(\large{ in }\) \(\large{ mm }\)
\(\large{ A_c }\) = area cross-section of flow \(\large{ in^2 }\) \(\large{ mm^2 }\)
\(\large{ P_w }\) = wetting perimeter \(\large{ in }\) \(\large{ mm }\)
