Please actually solve the question not how to do instructions thank you. In an oedometer test on a $2cm$ thick sample, the following set of data was recorded under

constant stress of $800$kPa :

a$)$ Calculate coefficient of consolidation by Casagrande's method.

b$)$ Calculate coefficient of consolidation by Taylor's method. $($Do not be confused if the

answer is different from the answer in part a$)$

Void ratios at the end of the other load increments for this test are:

c$)$ Find preconsolidation pressure $($maximum past effective stress$),$ by Casagrande's method.

d$)$ Find preconsolidation pressure $($maximum past effective stress$),$ by Strain Energy method.

e$)$ Calculate compression index, compression ratio, recompression$/$reload index and reload

ratio. Assume the clay was normally consolidated in its natural state before sampling. $($Note

that when you plot the stress axis in log$-$scale, the numbers written on the axis are actual

stress values. So you still need to take their log in slope calculations$)$
