Dec 01, 2008 An example for a rotary dryer is Figure 1, courtesy of Maroulis. Using the flow sheet, one writes all of the governing equations and identifies all of the variables. As done by the authors, there are 25 equations with 41 variables (pp. 291–293).The difference gives the degrees of freedom—16 in the case of rotary drying.
