Detailed explanation-1: -The method of analyzing systems to see whether they are over or under-specified, or if they are well-defined, is called a degree of freedom analysis. It works as follows for mass balances on a single process: From your flowchart, determine the number of unknowns in the process.
Detailed explanation-2: -The degrees of freedom NF is the number or process variables that must be specified in order to be able to determine the remaining process variables.
Detailed explanation-3: -The degree of freedom (DOF) analysis is an important, indispensable component of chemical process design. The analysis, which essentially involves counting the number of process variables and the equations relating them, becomes particularly complicated for multistage separations processes.
