Degrees of freedom

Degrees of Freedom

  • If Nd = 0 : Then there is only one solution, the problem is not a true design problem as there is no room for optimization.

  • If Nd < 0 : Then the problem is over-specified and only a trivial solution is possible.

  • If Nd > 0 : Then the problem has an infinite number of possible solutions however the designer must assign values to Nd variables to solve the problem. The values assigned must come from research, codes, standards, rules of thumb and design experience.

  • 100 scfm of Atmospheric air must be heated up to 80oC for use in a downstream process.

    • What are our design options?

    • Use HYSYS to evaluate the possible options

    • Which would you choose and why
