# Wetted Perimeter of Triangular Channel Calculator

The triangular wetted perimeter is defined as the perimeter of the triangular cross sectional area that is wet. In triangular open channel cross section, two sides are sloped at the same angle. The Common shapes for open channel cross section include rectangle, trapezoid, triangle, and circle. Here is an online mechanical calculator to calculate the *wetted perimeter of a triangular hydraulic pipe channel.*
