Three geometrically identical Lysimeters $(\mathrm{A}, \mathrm{B}$ and $\mathrm{C})$ installed in a paddy field have uniform initial ponding depths of $12 \mathrm{~cm}$. After a week, the recorded water depths in $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ are $10.4 \mathrm{~cm}, 8.6 \mathrm{~cm},$ and $7.0 \mathrm{~cm},$ respectively. Rainfall received during this week is $15 \mathrm{~mm},$ and the crop coefficient of paddy is 0.94 . Lysimeter ' $\mathrm{A}$ ' has a closed bottom with no plant. Lysimeter 'B' has an open bottom with no plant. Lysimeter 'C' has an open bottom with paddy plants. Neglecting the boundary effects and groundwater contribution in the Lysimeters, the weekly potential evapotranspiration will be_____________ $\quad \mathrm{cm}$.
