WebAis the cross-sectionalarea of the flow, Pis the wetted perimeterof the cross-section. More intuitively, the hydraulic diameter can be understood as a function of the hydraulic radius RH, which is defined as the cross-sectional area of … WebFeb 24, 2024 · The wetted perimeter is the cross-sectional length of the channel that the water touches (and gets wet), hence its name. The larger the wetted perimeter is, the more area the water gets in contact with the channel. That results in the slowing down of the water flow. In open channel flow, the slope of the channel also affects the water flow rate.
