Top Widths given Section Factor Solution

STEP 0: Pre-Calculation Summary
Formula Used
Top Width = Section Factor of Parabola/(0.544331054*(Depth of Flow^1.5))
T = ZPara/(0.544331054*(df^1.5))
This formula uses 3 Variables
Variables Used
Top Width - (Measured in Meter) - Top Width is defined as the width at the top of the section.
Section Factor of Parabola - (Measured in Meter^2.5) - Section Factor of Parabola is ratio of normal to critical channel depth.
Depth of Flow - (Measured in Meter) - 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.
STEP 1: Convert Input(s) to Base Unit
Section Factor of Parabola: 4.339 Meter^2.5 --> 4.339 Meter^2.5 No Conversion Required
Depth of Flow: 3.3 Meter --> 3.3 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
T = ZPara/(0.544331054*(df^1.5)) --> 4.339/(0.544331054*(3.3^1.5))
Evaluating ... ...
T = 1.32970600134957
STEP 3: Convert Result to Output's Unit
1.32970600134957 Meter --> No Conversion Required
FINAL ANSWER
1.32970600134957 1.329706 Meter <-- Top Width

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.
