How to determine wetted perimeter
The wetted perimeter is the perimeter of the cross sectional area that is "wet". The length of line of the intersection of channel wetted surface with a cross sectional plane normal to the flow direction. The term wetted perimeter is common in civil engineering, environmental engineering, hydrology, geomorphology, and heat transfer applications; it is associated with the hydrauli… WebP w = wetted perimeter [m] Due to the reliance on the wetted perimeter, the Manning equation can account for the changing flow conditions as the water level in a channel or pipe varies. Using the cross-sectional area of flow, A, the volumetric flow rate can be estimated using the following formula: Where: Q = volumetric flowrate [m 3 /s]
