Wetted Perimeter of a Trapezoidal Channel Calculator

Wetted perimeter is the perimeter of the cross sectional area of a hydraulic pipe that is wet. When a channel is much wider compared to its depth, then the wetted perimeter is approximately equal to that of the channel width. A trapezoid shape is mostly used for manmade channels and the cross section of natural stream channels. Here is an online mechanical calculator to calculate the wetted perimeter of a trapezoidal hydraulic pipe channel.

Code to add this calci to your website

Just copy and paste the below code to your webpage where you want to display this calculator.

Formula:

p = b + 2 * ( ( ( t - b ) / 2 )² + h² )^{1 / 2}
Where, p = Wetted Perimeter of Trapezoidal Channel b = Bottom Width h = Liquid Depth T = Width of the Liquid Surface
