Radius of Pipe given Velocity of Flow in Pipe by Manning Formula Solution

STEP 0: Pre-Calculation Summary

Formula Used

Hydraulic Radius = ((Flow Velocity*Manning Coefficient)/(Hydraulic Gradient^(1/2)))^(3/2)
R_h = ((v_f*n)/(S^(1/2)))^(3/2)
This formula uses 4 Variables

Variables Used

Hydraulic Radius - (Measured in Meter) - Hydraulic Radius, in fluid mechanics, is the cross-sectional area of an open channel or pipe divided by the wetted perimeter.
Flow Velocity - (Measured in Meter per Second) - Flow Velocity refers to the speed at which a fluid, such as a liquid or gas, moves through a particular area within a given time.
Manning Coefficient - Manning Coefficient is dimensionless and varies depending on the type of channel or surface through which water flows.
Hydraulic Gradient - Hydraulic Gradient is a specific measurement of liquid pressure above a vertical datum.

STEP 1: Convert Input(s) to Base Unit

Flow Velocity: 11.96 Meter per Second --> 11.96 Meter per Second No Conversion Required
Manning Coefficient: 0.009 --> No Conversion Required
Hydraulic Gradient: 0.25 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_h = ((v_f*n)/(S^(1/2)))^(3/2) --> ((11.96*0.009)/(0.25^(1/2)))^(3/2)

Evaluating ... ...

R_h = 0.0998862082068991

STEP 3: Convert Result to Output's Unit

0.0998862082068991 Meter --> No Conversion Required

FINAL ANSWER

0.0998862082068991 ≈ 0.099886 Meter <-- Hydraulic Radius
