Question
The following time-compression data was obtained from an oedometer test during consolidation following the application of a load increment. If the thickness of the doubly drained sample is 17.0 mm, calculate the coefficient of consolidation using the Square Root Fitting Method and the Log Time Fitting Method.

| Dial Gauge Reading (mm) | Time    |
|-------------------------|---------|
| 8.99                    | 0       |
| 9.10                    | 6 sec   |
| 9.14                    | 12 sec  |
| 9.21                    | 30 sec  |
| 9.29                    | 1 min   |
| 9.39                    | 2 min   |
| 9.50                    | 4 min   |
| 9.65                    | 8 min   |
| 9.74                    | 20 min  |
| 9.77                    | 40 min  |
| 9.79                    | 100 min |

This table shows the relationship between the dial gauge reading (in millimeters) and time during the oedometer test. The data is used to determine the coefficient of consolidation for the sample. The Square Root Fitting Method and Log Time Fitting Method can be applied to analyze this data.
