Wetted Area given Section Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wetted Surface Area of Channel = Section Factor/sqrt(Hydraulic Depth)
A = Z/sqrt(D_Hydraulic)
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Wetted Surface Area of Channel - (Measured in Square Meter) - Wetted Surface Area of Channel [length^2] is the total area of outer surface in contact with the surrounding water.
Section Factor - (Measured in Meter^2.5) - Section Factor is ratio of normal to critical channel depth.
Hydraulic Depth - (Measured in Meter) - Hydraulic Depth is defined as depth which in contact with water.

STEP 1: Convert Input(s) to Base Unit

Section Factor: 6.8 Meter^2.5 --> 6.8 Meter^2.5 No Conversion Required
Hydraulic Depth: 3 Meter --> 3 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = Z/sqrt(D_Hydraulic) --> 6.8/sqrt(3)

Evaluating ... ...

A = 3.92598183048946

STEP 3: Convert Result to Output's Unit

3.92598183048946 Square Meter --> No Conversion Required

FINAL ANSWER

3.92598183048946 ≈ 3.925982 Square Meter <-- Wetted Surface Area of Channel

(Calculation completed in 00.006 seconds)
