Length of Pipe given Head Loss by Hazen Williams Formula Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Pipe = Head Loss/((6.78*Average Velocity in Pipe Fluid Flow^(1.85))/((Diameter of Pipe^(1.165))*Coefficient of Roughness of Pipe^(1.85)))
L_p = h_f/((6.78*v_avg^(1.85))/((D_p^(1.165))*C^(1.85)))
This formula uses 5 Variables

Variables Used

Length of Pipe - (Measured in Meter) - Length of Pipe describes the length of the pipe in which the liquid is flowing.
Head Loss - (Measured in Meter) - Head Loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system.
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.
Diameter of Pipe - (Measured in Meter) - Diameter of Pipe is the diameter of the pipe in which the liquid is flowing.
Coefficient of Roughness of Pipe - Coefficient of Roughness of Pipe is a dimensionless parameter used in environmental engineering, particularly in fluid mechanics and hydraulics.

STEP 1: Convert Input(s) to Base Unit

Head Loss: 1.2 Meter --> 1.2 Meter No Conversion Required
Average Velocity in Pipe Fluid Flow: 4.57 Meter per Second --> 4.57 Meter per Second No Conversion Required
Diameter of Pipe: 0.4 Meter --> 0.4 Meter No Conversion Required
Coefficient of Roughness of Pipe: 31.33 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_p = h_f/((6.78*v_avg^(1.85))/((D_p^(1.165))*C^(1.85))) --> 1.2/((6.78*4.57^(1.85))/((0.4^(1.165))*31.33^(1.85)))

Evaluating ... ...

L_p = 2.14305443465738

STEP 3: Convert Result to Output's Unit

2.14305443465738 Meter --> No Conversion Required

FINAL ANSWER

2.14305443465738 ≈ 2.143054 Meter <-- Length of Pipe
