Percentage of Sand given Unit Weight of Deposit Solution

Follow our step by step solution on how to calculate Percentage of Sand given Unit Weight of Deposit?

FIRST Step Consider the formula
psa=(Wav)-((psi100)(W2+B2log10(T)))-((pcl100)(W3+B3log10(T)))W1+B1log10(T)100
Next Step Substitute values of Variables
psa=(15.06kN/m³)-((35100)(19kN/m³+0.1log10(25Year)))-((31.3100)(16kN/m³+40log10(25Year)))16.4kN/m³+0.2log10(25Year)100
Next Step Convert Units
psa=(15060N/m³)-((35100)(19000N/m³+0.1log10(7.9E+8s)))-((31.3100)(16000N/m³+40log10(7.9E+8s)))16400N/m³+0.2log10(7.9E+8s)100
Next Step Prepare to Evaluate
psa=(15060)-((35100)(19000+0.1log10(7.9E+8)))-((31.3100)(16000+40log10(7.9E+8)))16400+0.2log10(7.9E+8)100
Next Step Evaluate
psa=20.0606144199288
LAST Step Rounding Answer
psa=20.0606
