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 Widths given Section Factor?

Top Widths given Section Factor calculator uses Top Width = Section Factor of Parabola/(0.544331054*(Depth of Flow^1.5)) to calculate the Top Width, Top Widths given Section Factor formula is defined as the width of section in channel at any point in direction perpendicular to flow. Top Width is denoted by T symbol.

How to calculate Top Widths given Section Factor using this online calculator? To use this online calculator for Top Widths given Section Factor, enter Section Factor of Parabola (Z_Para) & Depth of Flow (d_f) and hit the calculate button. Here is how the Top Widths given Section Factor calculation can be explained with given input values -> 1.329706 = 4.339/(0.544331054*(3.3^1.5)).

FAQ

What is Top Widths given Section Factor?

Top Widths given Section Factor formula is defined as the width of section in channel at any point in direction perpendicular to flow and is represented as T = Z_Para/(0.544331054*(d_f^1.5)) or Top Width = Section Factor of Parabola/(0.544331054*(Depth of Flow^1.5)). Section Factor of Parabola is ratio of normal to critical channel depth & 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 Widths given Section Factor?

Top Widths given Section Factor formula is defined as the width of section in channel at any point in direction perpendicular to flow is calculated using Top Width = Section Factor of Parabola/(0.544331054*(Depth of Flow^1.5)). To calculate Top Widths given Section Factor, you need Section Factor of Parabola (Z_Para) & Depth of Flow (d_f). With our tool, you need to enter the respective value for Section Factor 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 Section Factor 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 = 1.5*Wetted Surface Area of Parabola/Depth of Flow
