A fluid whose apparent viscosity increases with shear rate is termed as the _____________ fluid?
Correct answer: C. Dilatant
- A. Newtonian
- B. Viscous
- C. Dilatant
- D. Non-viscous
Explanation
A dilatant, or shear-thickening, fluid becomes more resistant to flow as shear rate increases, so its apparent viscosity rises. Newtonian fluids have constant viscosity, while viscous and non-viscous are not the specific rheological classifications required here.
