Wetted Perimeter given Central Angle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wetted Perimeter for Partial Flow = (pi*Diameter of Pipe*Central Angle)/(360*pi/180)
P_w = (pi*D_pipe*∠_central)/(360*pi/180)
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Diameter of Pipe: 2.64 Meter --> 2.64 Meter No Conversion Required
Central Angle: 120 Degree --> 2.0943951023928 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_w = (pi*D_pipe*∠_central)/(360*pi/180) --> (pi*2.64*2.0943951023928)/(360*pi/180)

Evaluating ... ...

P_w = 2.7646015351585

STEP 3: Convert Result to Output's Unit

2.7646015351585 Meter --> No Conversion Required

FINAL ANSWER

2.7646015351585 ≈ 2.764602 Meter <-- Wetted Perimeter for Partial Flow

What is Central Angle?

The central angle is the angle subtended at the center of a circular pipe by the arc length of the wetted perimeter when the pipe is partially filled. This angle is essential for calculating flow characteristics like hydraulic radius and flow area in partially filled pipes. It helps in determining the distribution of flow within the pipe, affecting flow velocity, friction, and overall hydraulic performance, ensuring accurate design and analysis of drainage or sewer systems.
