Conclusions About the Ideas Presented

There is more than one idea in the paper, although all of them are not followed by a clear 

To come to an end, whichever equations are used, either Equation (6.10) based on the principle of the infinite medium 1 or the membrane separating two media with a constant concentration on each side, in both cases the coefficient of convective transfer into the liquid is infinite. Let us also note that the diffusivity was estimated for a contaminant diffusing through the polystyrene at 200 °C.
