- 2.6: "Dimensional Analysis"
- Dimensional analysis is a way of getting some useful information about a problem when you cannot obtain an analytical solution and may not even know anything about the form of the solution, but you have some ideas about important physical effects or variables.
- 2.7: Significance of Reynolds Numbers and Froude Numbers
- Some further insight into the significance of Reynolds numbers and Froude numbers is afforded by showing that dimensionless variables of this form always arise in problems involving viscous forces and gravity forces.
