Porosity given Dry Unit Weight in Porosity Solution

Follow our step by step solution on how to calculate Porosity given Dry Unit Weight in Porosity?

FIRST Step Consider the formula

η = 1 - (\frac{γ dry}{G s \cdot γ w})

Next Step Substitute values of Variables

∴

η = 1 - (\frac{12.99kN/m³}{2.65 \cdot 9810N/m³})

Next Step Convert Units

∴

η = 1 - (\frac{12990N/m³}{2.65 \cdot 9810N/m³})

Next Step Prepare to Evaluate

∴

η = 1 - (\frac{12990}{2.65 \cdot 9810})

Next Step Evaluate

∴

η = 0.500317350412556

LAST Step Rounding Answer

∴

η = 0.5003
