Venturi tube (w/ camera) Fluid Flow is inherently complex. ~ 10 23 atoms/cm 3 . Relative internal motion is often important 1. Fluid Parameters Important to Flow (Dynamics) density ρ [kg/m 3 ] viscosity η [kg/(m s)] Two cylinders with marbles demo compressibility P P V V C ∆ ∆ = ∆ ∆ − = ρ ρ 1 1 [1/Pa] Can measure compressibility using a closed container A F P = ∆ , x A V ∆ − = ∆ Æ x F V A A F x A V C ∆ = ∆ − − = 2 1 Clicker question 1. Can have smooth flow here. What happens downstream? Can be quite complex! F x ∆ A V V ∆ Lecture 27 pls-27.2 2. Characterization of Flow A.
