Data from a single load increment during a consolidation test on a $3/4-$in$.-$thick sample with drainage on both ends follow: Elapsed Time $($minutes$)1/41481630601202404801200$

Deformation Dial $(0\mathrm{.}0001$ in$.)16001582154415101465141013301269123212101200$

a$.)$Determine the coefficient of consolidation using square root of time method.

b$.)$Determine the coefficient of consolidation using the logarithm of time method.

Can you pls explain the solution step by step
