Remember its main purpose.
Question 5.
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.
Show hintHide hint
Consider how each variable interacts.
Question 6.
If the density of a fluid changes, how might this affect the selection of variables in dimensional analysis?
Show hintHide hint
Think about how density represents mass per volume.
