Width of Section given Perimeter Solution

STEP 0: Pre-Calculation Summary
Formula Used
Width of Section of Rect Channel = Wetted Perimeter of Rectangle-2*Depth of Flow of Channel
Brect = Prect-2*Df
This formula uses 3 Variables
Variables Used
Width of Section of Rect Channel - (Measured in Meter) - Width of Section of Rect Channel is the width of the rectangular cross-section of the beam parallel to the axis in consideration.
Wetted Perimeter of Rectangle - (Measured in Meter) - Wetted Perimeter of Rectangle is defined as the surface of the channel bottom and sides in direct contact with the aqueous body.
Depth of Flow of Channel - (Measured in Meter) - Depth of Flow of Channel is the distance from the top or surface of the flow to the bottom of a channel or other waterway or Depth of Flow at the Vertical while measuring Sound Weights.
STEP 1: Convert Input(s) to Base Unit
Wetted Perimeter of Rectangle: 20.8 Meter --> 20.8 Meter No Conversion Required
Depth of Flow of Channel: 5.2 Meter --> 5.2 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Brect = Prect-2*Df --> 20.8-2*5.2
Evaluating ... ...
Brect = 10.4
STEP 3: Convert Result to Output's Unit
10.4 Meter --> No Conversion Required
FINAL ANSWER
10.4 Meter <-- Width of Section of Rect Channel
(Calculation completed in 00.004 seconds)

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.
