Mass balance can also be described with a simplified equation (2). (2) In (2), all the materials that are fed into the process unit are considered the input and all the product streams that flow out of the process unit are considered the output.Generation is the amount of materials formed in a process unit and consumption is the amount of materials lost in a process unit.
