Area of Section of Open Channel Considering Condition of Minimum Specific Energy Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cross-Sectional Area of Channel = (Discharge of Channel*Top Width/[g])^(1/3)
A_cs = (Q*T/[g])^(1/3)
This formula uses 1 Constants, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Cross-Sectional Area of Channel - (Measured in Square Meter) - Cross-Sectional Area of Channel is the area of a two-dimensional shape that is obtained when a three-dimensional shape is sliced perpendicular to some specified axis at a point.
Discharge of Channel - (Measured in Cubic Meter per Second) - Discharge of Channel is the rate of flow of a liquid.
Top Width - (Measured in Meter) - Top Width is defined as the width at the top of the section.

STEP 1: Convert Input(s) to Base Unit

Discharge of Channel: 14 Cubic Meter per Second --> 14 Cubic Meter per Second No Conversion Required
Top Width: 2.1 Meter --> 2.1 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_cs = (Q*T/[g])^(1/3) --> (14*2.1/[g])^(1/3)

Evaluating ... ...

A_cs = 1.4419234946896

STEP 3: Convert Result to Output's Unit

1.4419234946896 Square Meter --> No Conversion Required

FINAL ANSWER

1.4419234946896 ≈ 1.441923 Square Meter <-- Cross-Sectional Area of Channel
