How to compare experimental and simulated evaporation rates

I recently read some papers on water evaporation simulation, but I found that the evaporation flux, which is calculated based on the simulation, was not compared with the experimental evaporation rate, the reason maybe that evaporation is actually accompanied by condensation. And the actual net evaporation rate will be much less than the simulated evaporation flux. Based on this, I would like to ask if Is there a way to relate simulated evaporation fluxes to experimental values?

Sorry, but this kind of question is off-topic here, since this is about the science you are trying to do and not about anything that is specific to LAMMPS. Rather than discussing this with people that know how to run LAMMPS, you should discuss with people that know about your area of research.
