Dear sir,
Thank you very much for your kind response to my request.

I have seen the simulation and I have some questions and some comments.

1) What is “minr” ? I changed its values but I couldn’t see the difference.
2) I would expect to see all the water of the open container to be evaporated (after some time) while the water of the closed container to lower its level and finally to remain constant. This does not happen. Why?
3) Is possible to change “vmax” with “temperature” ?
4) In case of a constant temperature (vmax) in the open container, the relationship between the number of liquid water molecules and time must be linear (constant evaporation rate).
