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
B_rect = P_rect-2*D_f
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

Depth of Flow given Hydraulic Radius in Rectangle

Go Depth of Flow of Channel = Width of Section of Rect Channel*Hydraulic Radius of Rectangle/(Width of Section of Rect Channel-2*Hydraulic Radius of Rectangle)

Hydraulic Radius of Open Channel

Go Hydraulic Radius of Rectangle = (Width of Section of Rect Channel*Depth of Flow of Channel)/(Width of Section of Rect Channel+2*Depth of Flow of Channel)

Width of Section given Hydraulic Radius of Rectangle

Go Width of Section of Rect Channel = (2*Hydraulic Radius of Rectangle*Depth of Flow of Channel)/(Depth of Flow of Channel-Hydraulic Radius of Rectangle)

Depth of Flow given Section Factor for Rectangle Channel

Go Depth of Flow of Channel = (Section Factor of Rectangle/Width of Section of Rect Channel)^(2/3)

Depth of Flow given Wetted Perimeter for Rectangle

Go Depth of Flow of Channel = (Wetted Perimeter of Rectangle-Width of Section of Rect Channel)*0.5

Width of Section given Section Factor

Go Width of Section of Rect Channel = Section Factor of Rectangle/(Depth of Flow of Channel^1.5)

Depth of Flow given Wetted Area for Rectangle

Go Depth of Flow of Channel = Wetted Surface Area of Rectangle/Width of Section of Rect Channel

Width of Section given Wetted Areas

Go Width of Section of Rect Channel = Wetted Surface Area of Rectangle/Depth of Flow of Channel

Wetted Area for Rectangle

Go Wetted Surface Area of Rectangle = Width of Section of Rect Channel*Depth of Flow of Channel

Wetted Perimeter for Rectangular Section

Go Wetted Perimeter of Rectangle = Width of Section of Rect Channel+2*Depth of Flow of Channel

Width of Section given Perimeter

Go Width of Section of Rect Channel = Wetted Perimeter of Rectangle-2*Depth of Flow of Channel

Section Factor for Rectangle

Go Section Factor of Rectangle = Width of Section of Rect Channel*Depth of Flow of Channel^1.5

Width of Section given Perimeter Formula

Width of Section of Rect Channel = Wetted Perimeter of Rectangle-2*Depth of Flow of Channel
B_rect = P_rect-2*D_f

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.
