Wetted Perimeter

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

hydraulic wettedWetting perimeter is the portion of the channel that is in contact with the fluid flowing.

Wetted perimeter Formula

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

Where:

\(\large{ P_w }\) = wetting perimeter

\(\large{ A }\) = cross-section flow area

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