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

Heat and Mass Balance EnggCyclopedia

Heat and mass balance is a document produced by process design engineers while designing a process plant. Sometimes heat and mass balance is not a separate document but appears alongside the Process Flow Diagram (PFD). A heat and mass balance sheet represents every process stream on the corresponding PFD in terms of the process conditions.
