Central Angle given Wetted Perimeter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Central Angle = (Wetted Perimeter*(360*pi/180))/(pi*Diameter of Pipe)
∠_central = (P*(360*pi/180))/(pi*D_pipe)
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 - (Measured in Meter) - Wetted Perimeter is defined as the surface of the channel bottom and sides in direct contact with the aqueous body.
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: 80 Meter --> 80 Meter No Conversion Required
Diameter of Pipe: 204 Meter --> 204 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

∠_central = (P*(360*pi/180))/(pi*D_pipe) --> (80*(360*pi/180))/(pi*204)

Evaluating ... ...

∠_central = 0.784313725490196

STEP 3: Convert Result to Output's Unit

0.784313725490196 Radian -->44.9378662847789 Degree (Check conversion here)

FINAL ANSWER

44.9378662847789 ≈ 44.93787 Degree <-- Central Angle
