← ScienceWhich outcome results when a non-Newtonian fluid, like paint, experiences high shear stress in a manufacturing turbine mixer?
A)Decreased viscosity due to shear thinning✓
B)Increased thermal expansion coefficient value
C)Cavitation erosion of impeller blades
D)Increased fluid density, causing sedimentation
💡 Explanation
Decreased viscosity occurs because *shear thinning* reduces resistance to flow under stress leading to improved mixing; therefore, paint viscosity drops, rather than thickening or causing cavitation because of flow dynamics.
