Self Cleansing Velocity Solution

Follow our step by step solution on how to calculate Self Cleansing Velocity?

FIRST Step Consider the formula

v s = C \cdot \sqrt{k \cdot d' \cdot (G - 1)}

Next Step Substitute values of Variables

∴

v s = 15 \cdot \sqrt{0.04 \cdot 4.8mm \cdot (1.3 - 1)}

Next Step Convert Units

∴

v s = 15 \cdot \sqrt{0.04 \cdot 0.0048m \cdot (1.3 - 1)}

Next Step Prepare to Evaluate

∴

v s = 15 \cdot \sqrt{0.04 \cdot 0.0048 \cdot (1.3 - 1)}

Next Step Evaluate

∴

v s = 0.113841995766062m/s

LAST Step Rounding Answer

∴

v s = 0.1138m/s
