Figure 11 shows the effect of spacing factor on PEEQ penetration depth, for maximum pore diameter equal to 50 μm. This data corresponds to the last three rows of Table 3, and is shown using white markers with a black outline. The data set of the fourth row of Table 3, being common to both Figure 10 and 11, is shown with solid black markers. The dashed trend line suggests an inverse relationship.
The complete data set is presented in Figure 12, for maximum pore diameter divided by the spacing factor. Each parameter set is shown using the same marker shape and colour as used in Figures 10 and 11. Again, the dashed line shows the linear trend.
