Study Notes
Fluid Dynamics
- Viscosity is the concept related to the resistance to flow exhibited by a fluid.
Non-Newtonian Fluids
- Thixotropic fluids exhibit a decrease in viscosity over time when subjected to constant stress.
Newton's Law of Viscosity
- Describes the linear relationship between the shear stress and shear rate of a fluid.
Fluid Behavior
- Newtonian fluids exhibit a constant viscosity regardless of the shear rate.
Material Behavior
- The yield point is the term for the point at which a material transitions from elastic to viscous behavior under stress.
