hydraulic radius of a pipe less than half

Hydraulic Radius of a Partially Full Pipe (Less than Half Full) Formula
\( r_h \;=\; \dfrac{ A_c }{ P_w }\) \( A_c \;=\; r_h \cdot P_w \) \( P_w \;=\; \dfrac{ A_c }{ r_h }\)
Symbol	English	Metric
\( r_h \) = hydraulic radius	\( in \)	\( mm \)
\( A_c \) = area cross-section of flow	\( in^2 \)	\( mm^2 \)
\( P_w \) = wetting perimeter	\( in \)	\(mm \)
