Average Unit Weight of Soil given Net Ultimate Bearing Capacity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Average Unit Weight = (Safe Bearing Capacity-(Net Ultimate Bearing Capacity in Soil/Factor of Safety in Soil Mechanics))/Depth of Footing in Soil
γavg = (qsa-(qnet/Fs))/Dfooting
This formula uses 5 Variables
Variables Used
Average Unit Weight - (Measured in Newton per Cubic Meter) - Average Unit Weight is the average of the values of unit weight that we get from different test cases.
Safe Bearing Capacity - (Measured in Pascal) - Safe Bearing Capacity is the maximum pressure which the soil can carry safely without risk of shear failure.
Net Ultimate Bearing Capacity in Soil - (Measured in Pascal) - Net Ultimate Bearing Capacity in Soil is the minimum net pressure intensity causing shear failure.
Factor of Safety in Soil Mechanics - Factor of Safety in Soil Mechanics is a dimensionless number defined as the ratio of the soil's shear strength (or the strength of a geotechnical structure) to the actual stress or load applied to it.
Depth of Footing in Soil - (Measured in Meter) - Depth of Footing in Soil is the longer dimension of the footing in soil mechanics.
STEP 1: Convert Input(s) to Base Unit
Safe Bearing Capacity: 36.34 Kilonewton per Square Meter --> 36340 Pascal (Check conversion ​here)
Net Ultimate Bearing Capacity in Soil: 38.3 Kilonewton per Square Meter --> 38300 Pascal (Check conversion ​here)
Factor of Safety in Soil Mechanics: 2.8 --> No Conversion Required
Depth of Footing in Soil: 2.54 Meter --> 2.54 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
γavg = (qsa-(qnet/Fs))/Dfooting --> (36340-(38300/2.8))/2.54
Evaluating ... ...
γavg = 8921.82227221597
STEP 3: Convert Result to Output's Unit
8921.82227221597 Newton per Cubic Meter -->8.92182227221597 Kilonewton per Cubic Meter (Check conversion ​here)
FINAL ANSWER
8.92182227221597 8.921822 Kilonewton per Cubic Meter <-- Average Unit Weight
