Proportionate Perimeter given Central Angle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Proportionate perimeter = (Central Angle/(360*pi/180))
P_p = (∠_central/(360*pi/180))
This formula uses 1 Constants, 2 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Proportionate perimeter - Proportionate perimeter is the ratio of perimeter while running partially full to running full.
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

Central Angle: 120 Degree --> 2.0943951023928 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_p = (∠_central/(360*pi/180)) --> (2.0943951023928/(360*pi/180))

Evaluating ... ...

P_p = 0.33333333333327

STEP 3: Convert Result to Output's Unit

0.33333333333327 --> No Conversion Required

FINAL ANSWER

0.33333333333327 ≈ 0.333333 <-- Proportionate perimeter

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.
