Figure 6.
The image presents a line graph that plots sample average saturation degree denoted as S over a logarithmic scale of time t measured in hours. The vertical axis ranges from 0.70 to 1, while the horizontal axis extends from 10 to the power of 0 to 10 to the power of 5. Each curve represents different square sizes, 10 by 10 millimetres squared represented by a solid line, 20 by 20 millimetres squared with a dashed line, 40 by 40 millimetres squared as a dash dot line, and 80 by 80 millimetres squared illustrated with a dotted line. The graph visualises the relationship between saturation degree and time through clearly differentiated line styles.Time evolution of sample average saturation degree, , for different sample sizes under condition HP2D
