Dry Unit Weight given Percentage of Air Voids Solution

Follow our step by step solution on how to calculate Dry Unit Weight given Percentage of Air Voids?

FIRST Step Consider the formula

γ dry = (1 - n a) \cdot G s \cdot \frac{γ water}{1 + w s \cdot G s}

Next Step Substitute values of Variables

∴

γ dry = (1 - 0.2) \cdot 2.65 \cdot \frac{9.81kN/m³}{1 + 8.3 \cdot 2.65}

Next Step Convert Units

∴

γ dry = (1 - 0.2) \cdot 2.65 \cdot \frac{9810N/m³}{1 + 8.3 \cdot 2.65}

Next Step Prepare to Evaluate

∴

γ dry = (1 - 0.2) \cdot 2.65 \cdot \frac{9810}{1 + 8.3 \cdot 2.65}

Next Step Evaluate

∴

γ dry = 904.422700587084N/m³

Next Step Convert to Output's Unit

∴

γ dry = 0.904422700587084kN/m³

LAST Step Rounding Answer

∴

γ dry = 0.9044kN/m³
