MASS BALANCES - University of Washington

Mass balances take several forms. In some systems, no material enters or leaves the CV, and the rate of change is not considered important. In such systems, the mass balance simply states that everything that was present in the system at some initial time must be there at all later times, albeit perhaps in different forms.
