  • 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
