What is Wetted Perimeter?
The wetted perimeter is the length of the boundary in contact with the fluid in a cross-sectional area of a channel, pipe, or conduit. It plays a key role in calculating the hydraulic radius, which influences flow velocity and friction losses. In open channels and partially filled pipes, the wetted perimeter varies with the flow depth, affecting the system's efficiency and capacity. Accurate determination of the wetted perimeter is crucial for the design and analysis of efficient drainage, sewer, and water conveyance systems.
How to Calculate Central Angle given Wetted Perimeter?
Central Angle given Wetted Perimeter calculator uses Central Angle = (Wetted Perimeter for Partial Flow*(360*pi/180))/(pi*Diameter of Pipe) to calculate the Central Angle, The Central Angle given Wetted Perimeter is defined as the angle subtended at the center of a circular pipe by the arc length of the wetted perimeter when the pipe is partially filled. Central Angle is denoted by ∠central symbol.
