Void Ratio given Total Pressure per unit Area for Dams on Soft Foundations Solution

STEP 0: Pre-Calculation Summary
Formula Used
Void Ratio = (Degree of Saturation-(Total Pressure at given Point/(Depth of Dam*Specific Weight of Water in KN per cubic meter)))/((Total Pressure at given Point/(Depth of Dam*Specific Weight of Water in KN per cubic meter))-1)
e = (S-(P0/(D*W)))/((P0/(D*W))-1)
This formula uses 5 Variables
Variables Used
Void Ratio - Void Ratio is the ratio of the volume of voids to the volume of solids.
Degree of Saturation - Degree of Saturation is the ratio of the volume of water to the volume of voids.
Total Pressure at given Point - (Measured in Pascal) - Total Pressure at given Point in a flow is the pressure that would exist if the flow were slowed down isotropically to zero velocity.
Depth of Dam - (Measured in Meter) - Depth of Dam is the distance from the top or surface to the bottom of something.
Specific Weight of Water in KN per cubic meter - (Measured in Kilonewton per Cubic Meter) - Specific Weight of Water in KN per cubic meter is the weight per unit volume of water.
STEP 1: Convert Input(s) to Base Unit
Degree of Saturation: 7 --> No Conversion Required
Total Pressure at given Point: 109.6 Pascal --> 109.6 Pascal No Conversion Required
Depth of Dam: 3 Meter --> 3 Meter No Conversion Required
Specific Weight of Water in KN per cubic meter: 9.81 Kilonewton per Cubic Meter --> 9.81 Kilonewton per Cubic Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
e = (S-(P0/(D*W)))/((P0/(D*W))-1) --> (7-(109.6/(3*9.81)))/((109.6/(3*9.81))-1)
Evaluating ... ...
e = 1.20256953972808
STEP 3: Convert Result to Output's Unit
1.20256953972808 --> No Conversion Required
FINAL ANSWER
1.20256953972808 1.20257 <-- Void Ratio
