This formula uses 1 Constants, 3 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
Central Angle - (Measured in Radian) - A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B.
Wetted Perimeter for Partial Flow - (Measured in Meter) - Wetted Perimeter for Partial Flow refers to the length of the pipe or channel's inner surface that is in contact with the flowing fluid when it is not running full.
Diameter of Pipe - (Measured in Meter) - Diameter of Pipe is the diameter of the pipe in which the liquid is flowing.
STEP 1: Convert Input(s) to Base Unit
Wetted Perimeter for Partial Flow: 6.25 Meter --> 6.25 Meter No Conversion Required

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.
