Question

Based on the rheological behavior of fluid, all of the following shows time independent property, except:

• A. Plastic
• B. Anti-thixotropic
• C. Pseudoplastic
• D. Non-newtonian

Hint:

Anti-thixotropic fluids become thicker with time under constant shear, unlike time-independent fluids like plastic and pseudoplastic, which maintain a consistent flow behavior.

Answer 1

The Correct Option is B

Anti-thixotropic fluids exhibit a time-dependent behavior, meaning their viscosity increases over time when subjected to constant shear. This is in contrast to plastic, pseudoplastic, and non-Newtonian fluids, which can exhibit time-independent properties.
