Answer the following question given this paragraph: 

12.4 Viscosity and Laminar Flow; Poiseuille’s Law • Laminar flow is characterized by smooth flow of the fluid in layers that do not mix. • Turbulence is characterized by eddies and swirls that mix layers of fluid together. • Fluid viscosity η is due to friction within a fluid. Representative values are given in Table 12.1. Viscosity has units of.


Q: What property is characterized by eddies and swirls that mix layers of fluid together, unlike laminar flow?


A:
turbulence
