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)
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

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.
Subtended Angle in Radians - (Measured in Radian) - Subtended Angle in Radians is the angle made by something from a given viewpoint.
Wetted Surface Area of Circular Channel - (Measured in Square Meter) - Wetted Surface Area of Circular Channel [length^2] is the total area of outer surface in contact with the surrounding water.

STEP 1: Convert Input(s) to Base Unit

Subtended Angle in Radians: 3.14 Degree --> 0.0548033385126116 Radian (Check conversion here)
Wetted Surface Area of Circular Channel: 0.221 Square Meter --> 0.221 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_section = sqrt(((180/pi)*(θ_Angle)-(8*A_w(cir)))/sin(θ_Angle)) --> sqrt(((180/pi)*(0.0548033385126116)-(8*0.221))/sin(0.0548033385126116))

Evaluating ... ...

d_section = 5.00474847169947

STEP 3: Convert Result to Output's Unit

5.00474847169947 Meter --> No Conversion Required

FINAL ANSWER

5.00474847169947 ≈ 5.004748 Meter <-- Diameter of Section

What is Wetted Area?

The surface area that interacts with the working fluid or gas. In maritime use, the wetted area is the area of the hull which is immersed in water. In aeronautics, the wetted area is the area which is in contact with the external airflow. This has a direct relationship on the overall aerodynamic drag of the aircraft.
