Self Cleaning Invert Slope Solution

Follow our step by step solution on how to calculate Self Cleaning Invert Slope?

FIRST Step Consider the formula

sL I = (\frac{k}{m}) \cdot (G - 1) \cdot d'

Next Step Substitute values of Variables

∴

sL I = (\frac{0.04}{10m}) \cdot (1.3 - 1) \cdot 4.8mm

Next Step Convert Units

∴

sL I = (\frac{0.04}{10m}) \cdot (1.3 - 1) \cdot 0.0048m

Next Step Prepare to Evaluate

∴

sL I = (\frac{0.04}{10}) \cdot (1.3 - 1) \cdot 0.0048

Next Step Evaluate

∴

sL I = 5.76E-06

LAST Step Rounding Answer

∴

sL I = 5.8E-6
