Mass balance Wikipedia
A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem

Fundamentals of Paper Drying Theory and Application from
Paper drying is associated with both heat and mass transfer. The heat energy released when steam condense s is transmitted through the dryer shell to the wet paper and this constitutes the heat transfer aspect of drying. The air receives the water vapour evaporated from the paper. The re moval of this vapour fr om the sheet into the air stream
