The variation of the dynamic viscosity for a fluid is given as \({\rm{\mu }} = {\rm{A}}{{\rm{e}}^{\left( {\frac{{\rm{B}}}{{\rm{T}}}} \right)}}\). Where A and B are fluid constant, µ = viscosity and T = temperature.
If the initial temperature is T and the percentage change in temperature is t0, then the percentage change in the permeability of the soil is given by:1
\({\rm{\;}}\frac{{{\rm{AB}}}}{{\rm{T}}} \times {{\rm{t}}_0}\)
2
\({\rm{\;}}\frac{{\rm{B}}}{{{{\rm{T}}^2}}} \times {{\rm{t}}_0}\)
3
\(\frac{{\rm{B}}}{{\rm{T}}} \times {{\rm{t}}_0}\)
4
\({\rm{\;}}\frac{{\rm{B}}}{{\rm{T}}} \times {{\rm{e}}^{\left( {\frac{{\rm{B}}}{{\rm{T}}}} \right)}} \times {{\rm{t}}_0}\)
