Hydraulic Gradient given Mean Velocity of Flow Solution

STEP 0: Pre-Calculation Summary

Formula Used

Hydraulic Gradient = (Average Velocity in Pipe Fluid Flow/(0.85*Coefficient of roughness of pipe*((Pipe Radius)^(0.63))))^(1/0.54)
S = (v_avg/(0.85*C*((R)^(0.63))))^(1/0.54)
This formula uses 4 Variables

Variables Used

Hydraulic Gradient - Hydraulic gradient is a specific measurement of liquid pressure above a vertical datum.
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 constant term.
Pipe Radius - (Measured in Meter) - The Pipe Radius is the radius of the pipe through which the fluid is flowing.

STEP 1: Convert Input(s) to Base Unit

Average Velocity in Pipe Fluid Flow: 4.57 Meter per Second --> 4.57 Meter per Second No Conversion Required
Coefficient of roughness of pipe: 31.33 --> No Conversion Required
Pipe Radius: 200 Millimeter --> 0.2 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = (v_avg/(0.85*C*((R)^(0.63))))^(1/0.54) --> (4.57/(0.85*31.33*((0.2)^(0.63))))^(1/0.54)

Evaluating ... ...

S = 0.250000402443848

STEP 3: Convert Result to Output's Unit

0.250000402443848 --> No Conversion Required

FINAL ANSWER

0.250000402443848 ≈ 0.25 <-- Hydraulic Gradient
