The relationship between co-efficient of consolidation Cv, time factor Tv, drainage path d, and time t is given by
1
\({{\rm{C}}_{\rm{v}}}{\rm{ = }}\frac{{{\rm{Tv\ t}}}}{{{{\rm{d}}^{\rm{2}}}}}\)
2
\({{\rm{C}}_{\rm{v}}}{\rm{ = }}\frac{{{\rm{t}}\ {{\rm{d}}^2}}}{{{\rm{Tv}}}}\)
3
\({{\rm{C}}_{\rm{v}}}{\rm{ = }}\frac{{{\rm{Tv}}\ {{\rm{d}}^2}}}{{\rm{t}}}\)
4
\({{\rm{C}}_{\rm{v}}}{\rm{ = }}\frac{{{\rm{Tv}}}}{{{{\rm{d}}^2}{\rm{t}}}}\)
