Challenge Problems
Push your limits with advanced challenges
Given a new hydraulic system with variables: pressure (P), flow rate (Q), and viscosity (µ), analyze how these relate through dimensionless groups. Formulate the relevant pi terms and explain the selection of repeating variables.
💡 Hint: Consider how each variable interacts.
If the density of a fluid changes, how might this affect the selection of variables in dimensional analysis?
