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

\( r_h =   A_c \;/\; P_w \) 

\( A_c =  r_h \; P_w \) 

\( P_w =  A_c \;/\; r_h \) 

Solve for rh

area cross-section, Ac
wetting perimeter, Pw

Solve for Ac

hydraulic radius, rh
wetting perimeter, Pw

Solve for Pw

area cross-section, Ac
hydraulic radius, rh

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