Percentage of Silt for Unit Weight of Deposits Solution

STEP 0: Pre-Calculation Summary

Formula Used

Percentage of Silt = ((Average Unit Weight of Deposit)-((Percentage of Sand/100)*(Unit Weight of Sand+Constant B1*log10(Age of Sediment)))-((Percentage of Clay/100)*(Unit Weight of Clay+Constant B3*log10(Age of Sediment))))/((Unit Weight of Silt+Constant B2*log10(Age of Sediment))/100)
p_si = ((W_av)-((p_sa/100)*(W₁+B₁*log10(T)))-((p_cl/100)*(W₃+B₃*log10(T))))/((W₂+B₂*log10(T))/100)
