Mean Velocity of Flow in Pipe by Hazen Williams Formula Solution

STEP 0: Pre-Calculation Summary

Formula Used

Average Velocity in Pipe Fluid Flow = 0.85*Coefficient of Roughness of Pipe*((Pipe Radius)^(0.63))*(Hydraulic Gradient)^(0.54)
v_avg = 0.85*C*((R)^(0.63))*(S)^(0.54)
This formula uses 4 Variables

Variables Used

Average Velocity in Pipe Fluid Flow - (Measured in Meter per Second) - Average Velocity in Pipe Fluid Flow is the total volumetric flow rate divided by the cross-sectional area of the pipe.
Coefficient of Roughness of Pipe - Coefficient of Roughness of Pipe is a dimensionless parameter used in environmental engineering, particularly in fluid mechanics and hydraulics.
Pipe Radius - (Measured in Meter) - The Pipe Radius is the radius of the pipe through which the fluid is flowing.
Hydraulic Gradient - Hydraulic Gradient is a specific measurement of liquid pressure above a vertical datum.

STEP 1: Convert Input(s) to Base Unit

Coefficient of Roughness of Pipe: 31.33 --> No Conversion Required
Pipe Radius: 200 Millimeter --> 0.2 Meter (Check conversion here)
Hydraulic Gradient: 0.25 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

v_avg = 0.85*C*((R)^(0.63))*(S)^(0.54) --> 0.85*31.33*((0.2)^(0.63))*(0.25)^(0.54)

Evaluating ... ...

v_avg = 4.56999602740121

STEP 3: Convert Result to Output's Unit

4.56999602740121 Meter per Second --> No Conversion Required

FINAL ANSWER

4.56999602740121 ≈ 4.569996 Meter per Second <-- Average Velocity in Pipe Fluid Flow
