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.

How to Calculate Top Width for Parabola?

Top Width for Parabola calculator uses Top Width = 1.5*Wetted Surface Area of Parabola/Depth of Flow to calculate the Top Width, The Top Width for Parabola is defined as the width of section in the channel at any point in the direction perpendicular to the flow. Top Width is denoted by T symbol.

How to calculate Top Width for Parabola using this online calculator? To use this online calculator for Top Width for Parabola, enter Wetted Surface Area of Parabola (A_Para) & Depth of Flow (d_f) and hit the calculate button. Here is how the Top Width for Parabola calculation can be explained with given input values -> 1.33 = 1.5*4.62/3.3.

FAQ

What is Top Width for Parabola?

The Top Width for Parabola is defined as the width of section in the channel at any point in the direction perpendicular to the flow and is represented as T = 1.5*A_Para/d_f or Top Width = 1.5*Wetted Surface Area of Parabola/Depth of Flow. Wetted Surface Area of Parabola [length^2] is the total area of outer surface in contact with the surrounding water & Depth of Flow 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.

How to calculate Top Width for Parabola?

The Top Width for Parabola is defined as the width of section in the channel at any point in the direction perpendicular to the flow is calculated using Top Width = 1.5*Wetted Surface Area of Parabola/Depth of Flow. To calculate Top Width for Parabola, you need Wetted Surface Area of Parabola (A_Para) & Depth of Flow (d_f). With our tool, you need to enter the respective value for Wetted Surface Area of Parabola & Depth of Flow and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Top Width?

In this formula, Top Width uses Wetted Surface Area of Parabola & Depth of Flow. We can use 3 other way(s) to calculate the same, which is/are as follows -

Top Width = Wetted Surface Area of Parabola/((2/3)*Depth of Flow)
Top Width = sqrt((8*(Depth of Flow)^2*Hydraulic Radius of Parabola)/(2*Depth of Flow-3*Hydraulic Radius of Parabola))
Top Width = Section Factor of Parabola/(0.544331054*(Depth of Flow^1.5))
