Friction Factor given Self Cleansing Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Friction Factor = (8*[g]*Dimensional Constant*Diameter of Particle*(Specific Gravity of Sediment-1))/(Self Cleansing Velocity)^2
f' = (8*[g]*k*d^'*(G-1))/(v_s)^2
This formula uses 1 Constants, 5 Variables

Constants Used

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

Variables Used

Friction Factor - The Friction Factor quantifies resistance to flow in a pipe due to surface roughness, impacting energy loss and velocity.
Dimensional Constant - Dimensional Constant indicates important characteristics of sediments present in the sewage. Its value usually varies from 0.04 (start of scouring of clean grit) to 0.08 (full removal of sticky grit).
Diameter of Particle - (Measured in Meter) - The Diameter of Particle is the straight-line distance across its widest point, typically measured in micrometers or millimeters.
Specific Gravity of Sediment - Specific Gravity of Sediment is the ratio of sediment particle density to the density of water, indicating its heaviness.
Self Cleansing Velocity - (Measured in Meter per Second) - Self Cleansing Velocity refers to the minimum speed at which fluid must flow in a sewer to prevent sediment deposition and maintain a clear path.

STEP 1: Convert Input(s) to Base Unit

Dimensional Constant: 0.04 --> No Conversion Required
Diameter of Particle: 4.8 Millimeter --> 0.0048 Meter (Check conversion here)
Specific Gravity of Sediment: 1.3 --> No Conversion Required
Self Cleansing Velocity: 0.114 Meter per Second --> 0.114 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f' = (8*[g]*k*d^'*(G-1))/(v_s)^2 --> (8*[g]*0.04*0.0048*(1.3-1))/(0.114)^2

Evaluating ... ...

f' = 0.347715013850416

STEP 3: Convert Result to Output's Unit

0.347715013850416 --> No Conversion Required

FINAL ANSWER

0.347715013850416 ≈ 0.347715 <-- Friction Factor

What is self cleansing velocity ?

Self-cleansing velocity is the minimum flow velocity required in a sewer or drainage system to prevent sediment from settling and accumulating. This ensures that the system remains clear of blockages, reducing the need for maintenance. The self-cleansing velocity depends on factors such as pipe material, diameter, and the type of sediment present. Maintaining this velocity is crucial for the efficient operation and longevity of sewer systems, as it helps prevent clogs and backups.
