Bed Slope of Sewer given Flow Velocity by Manning's Formula Solution

STEP 0: Pre-Calculation Summary
Formula Used
Bed slope = ((Flow Velocity*Rugosity coefficient)/(Hydraulic mean depth)^(2/3))^2
s = ((Vf*n)/(m)^(2/3))^2
This formula uses 4 Variables
Variables Used
Bed slope - Bed slope of the sewer under consideration.
Flow Velocity - (Measured in Meter per Second) - Flow Velocity is the velocity of the flow of any fluid.
Rugosity coefficient - Rugosity coefficient depend upon the type of channel surface.
Hydraulic mean depth - (Measured in Meter) - The Hydraulic mean depth is defined as the area of the flow section divided by the top water surface width.
STEP 1: Convert Input(s) to Base Unit
Flow Velocity: 1.12 Meter per Second --> 1.12 Meter per Second No Conversion Required
Rugosity coefficient: 0.015 --> No Conversion Required
Hydraulic mean depth: 10 Meter --> 10 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
s = ((Vf*n)/(m)^(2/3))^2 --> ((1.12*0.015)/(10)^(2/3))^2
Evaluating ... ...
s = 1.31004203239887E-05
STEP 3: Convert Result to Output's Unit
1.31004203239887E-05 --> No Conversion Required
FINAL ANSWER
1.31004203239887E-05 1.3E-5 <-- Bed slope
