Lesson 8 Dimensional Analysis & Similitude


  • Concepts. Explain/apply key concepts1: Pi-group, Model, Prototype, Similitude, Geometric similitude, Dynamic similitude.
  • Procedural Knowledge.
    • Apply the Pi-Buckingham theorem to identify the # of pi groups.
    • Apply the step-by-step method to find pi-groups.
    • Relate pi-groups and/or variable between models and prototypes
  • Factual Knowledge.
    • Describe meaning of common pi-groups (Table 8.3).
