Pore Pressure Ratio given Horizontal Width Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pore Pressure Ratio = (Upward Force*Width of Soil Section)/Total Weight of Slice in Soil Mechanics
r_u = (u*w)/ΣW
This formula uses 4 Variables

Variables Used

Pore Pressure Ratio - Pore pressure ratio is a crude way of describing pore-water conditions in a slope stability analysis.
Upward Force - (Measured in Pascal) - Upward Force due to seepage water.
Width of Soil Section - (Measured in Meter) - Width of Soil Section is the measurement or extent of something from side to side.
Total Weight of Slice in Soil Mechanics - (Measured in Newton) - Total Weight of Slice in Soil Mechanics is Weight of the slice taken into the consideration.

STEP 1: Convert Input(s) to Base Unit

Upward Force: 20 Pascal --> 20 Pascal No Conversion Required
Width of Soil Section: 2.921 Meter --> 2.921 Meter No Conversion Required
Total Weight of Slice in Soil Mechanics: 59.8 Newton --> 59.8 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_u = (u*w)/ΣW --> (20*2.921)/59.8

Evaluating ... ...

r_u = 0.976923076923077

STEP 3: Convert Result to Output's Unit

0.976923076923077 --> No Conversion Required

FINAL ANSWER

0.976923076923077 ≈ 0.976923 <-- Pore Pressure Ratio

Pore Pressure Ratio given Horizontal Width Formula

LaTeX Go

Pore Pressure Ratio = (Upward Force*Width of Soil Section)/Total Weight of Slice in Soil Mechanics
r_u = (u*w)/ΣW

What is Shear Stress?

Shear stress, often denoted by τ (Greek: tau), is the component of stress coplanar with a material cross section. It arises from the shear force, the component of force vector parallel to the material cross section.
