Challenge Problems
Push your limits with challenges.
Question 1
Given a fluid flow problem with six variables: time period T, wavelength λ, depth D, density ρ, gravity g, and surface tension σ, derive the functional relationships among the dimensionless groups formed.
💡 Hint: Remember to first list all variables and their dimensions!
Question 2
In a system where pressure drop, velocity, density, and diameter interact, establish which variables could serve as repeating variables for dimensional analysis.
💡 Hint: Consider what happens to the terms if any overlapping relationships exist!
