Which 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.
