Dear friends
i searched many papers and books,and also internet

RE: calculation of liquid-film thickness
rhol liquid specific mass (kg/m3)
u velocity
delta film thicknerss
sigma surface tension of liquid
If you search the net with the Weber number keyword you should find lots of references.
I tend to use 8-13 as the critical number, but this may not be relevant for your case. Definitly check before!
Hope this helps
