Angle of Sector given Top Width Solution

STEP 0: Pre-Calculation Summary

Formula Used

Subtended Angle in Radians = 2*asin((Top Width of Circular Channel/Diameter of Section))
θ_Angle = 2*asin((T_cir/d_section))
This formula uses 2 Functions, 3 Variables

Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
asin - The inverse sine function, is a trigonometric function that takes a ratio of two sides of a right triangle and outputs the angle opposite the side with the given ratio., asin(Number)

Variables Used

Subtended Angle in Radians - (Measured in Radian) - Subtended Angle in Radians is the angle made by something from a given viewpoint.
Top Width of Circular Channel - (Measured in Meter) - Top Width of Circular Channel is defined as width at top of section.
Diameter of Section - (Measured in Meter) - The Diameter of Section refers to the length of the segment that passes through the center of the circle and touches two points on the edge of the circle.

STEP 1: Convert Input(s) to Base Unit

Top Width of Circular Channel: 0.137 Meter --> 0.137 Meter No Conversion Required
Diameter of Section: 5 Meter --> 5 Meter No Conversion Required

STEP 2: Evaluate Formula

What is Open Channel Flow?

Open-channel flow, a branch of hydraulics and fluid mechanics, is a type of liquid flow within a conduit or in channel with a free surface, known as a channel. The other type of flow within a conduit is pipe flow. These two types of flow are similar in many ways but differ in one important respect: the free surface.
