Pore Water Pressure given Pore Pressure Ratio Solution

Follow our step by step solution on how to calculate Pore Water Pressure given Pore Pressure Ratio?

FIRST Step Consider the formula

F u = (r u \cdot γ \cdot z)

Next Step Substitute values of Variables

∴

F u = (0.9 \cdot 18kN/m³ \cdot 3m)

Next Step Convert Units

∴

F u = (0.9 \cdot 18000N/m³ \cdot 3m)

Next Step Prepare to Evaluate

∴

F u = (0.9 \cdot 18000 \cdot 3)

Next Step Evaluate

∴

F u = 48600Pa

LAST Step Convert to Output's Unit

∴

F u = 48.6kN/m²
