Degrees of Freedom: Interactive Simulation

This simulation runs on your browser. Try to predict the behavior when a parameter changes before using a slider to change that parameter. A screencast explains how to use this simulation.

Simulation: Degree of Freedom Analysis on a Distillation Column

Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.

  1. If you increase the number of unknowns within the same problem, does the system move toward over- or underspecification?
  2. How are the number of degrees affected by the switch from using 1 – zA to zB as the species B representation? Explain.
