Hydraulic Radius of Open Channel Solution

STEP 0: Pre-Calculation Summary
Formula Used
Hydraulic Radius of Rectangle = (Width of Section of Rect Channel*Depth of Flow of Channel)/(Width of Section of Rect Channel+2*Depth of Flow of Channel)
RH(rect) = (Brect*Df)/(Brect+2*Df)
This formula uses 3 Variables
Variables Used
Hydraulic Radius of Rectangle - (Measured in Meter) - Hydraulic Radius of Rectangle is the ratio of the cross-sectional area of a channel or pipe in which a fluid is flowing to the wet perimeter of the conduit.
Width of Section of Rect Channel - (Measured in Meter) - Width of Section of Rect Channel is the width of the rectangular cross-section of the beam parallel to the axis in consideration.
Depth of Flow of Channel - (Measured in Meter) - Depth of Flow of Channel 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
Width of Section of Rect Channel: 10.4 Meter --> 10.4 Meter No Conversion Required
Depth of Flow of Channel: 5.2 Meter --> 5.2 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
RH(rect) = (Brect*Df)/(Brect+2*Df) --> (10.4*5.2)/(10.4+2*5.2)
Evaluating ... ...
RH(rect) = 2.6
STEP 3: Convert Result to Output's Unit
2.6 Meter --> No Conversion Required
FINAL ANSWER
2.6 Meter <-- Hydraulic Radius of Rectangle
(Calculation completed in 00.004 seconds)
