← ScienceWhich effect arises if industrial mixing blades run too fast?
A)Increased energy dissipation via viscous heating✓
B)Reduced mixing quality from laminar flow
C)Decreased shear stress within mixture
D)Elevated reaction rates within fluid
💡 Explanation
Increased speed causes greater *energy dissipation* because higher shear rates overcome viscous resistance, ultimately generating heat from the *viscosity*. The heat comes from mechanical effects, therefore energy dissipation increases rather than other mixing characteristics like quality if energy is lower.
