Length of Pipe given Head Loss due to Friction Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Pipe = (Head Loss*2*[g]*Diameter of Pipe)/(4*Darcy's Coefficient of Friction*(Average Velocity in Pipe Fluid Flow)^2)
L_p = (h_f*2*[g]*D_p)/(4*f*(v_avg)^2)
This formula uses 1 Constants, 5 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

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.
Diameter of Pipe - (Measured in Meter) - Diameter of Pipe is the diameter of the pipe in which the liquid is flowing.
Darcy's Coefficient of Friction - Darcy's Coefficient of Friction refers to a parameter used to characterize the flow of water or other fluids through porous media, such as soil or rock.
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.

STEP 1: Convert Input(s) to Base Unit

Head Loss: 1.2 Meter --> 1.2 Meter No Conversion Required
Diameter of Pipe: 0.4 Meter --> 0.4 Meter No Conversion Required
Darcy's Coefficient of Friction: 0.045 --> No Conversion Required
Average Velocity in Pipe Fluid Flow: 4.57 Meter per Second --> 4.57 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_p = (h_f*2*[g]*D_p)/(4*f*(v_avg)^2) --> (1.2*2*[g]*0.4)/(4*0.045*(4.57)^2)

Evaluating ... ...

L_p = 2.50430374736452

STEP 3: Convert Result to Output's Unit

2.50430374736452 Meter --> No Conversion Required

FINAL ANSWER

2.50430374736452 ≈ 2.504304 Meter <-- Length of Pipe
