Urgent!! Evaporation from liquid surface
 

hai friends

I would like to ask you a reference/equation/relation for evaporation of a liquid when subjected to heat flux on the containing tank/vessel into the region(ullage space) above the liquid partially filled in the tank. the ullage space is assumed te of same material that is a homogeneous fluid.

I hope you understand my enquiry.

I would like to use this relation in my analysis.
