Dimensionless groups are a handy tool to approach engineering problems – most commonly used by Mechanical Engineers but overall a generally applicable method of summarizing complex systems.
This document is a summary of many of the most commonly used dimensionless groups and includes a summary of the theory, derivation, and usage of these groups on page 7. This is just a small sample of the power of dimensionless groups, but would be a handy desk reference as well.
A special thank you to Dr. Graham Walker, who provided a version of this list to students for his class “Product Design for Manufacturing” at Columbia University.
