Correct Answer - Option 1 : dilatant fluid
Explanation:
Thixotropic Fluid:
Fluids for which dynamic viscosity decreases with the time are termed as thixotropic fluids.
Example- Lipstick, Crude Oil, etc.
Pseudoplastic Fluid:
Non-Newtonian fluid for which dynamic viscosity decreases with an increase in the shear stress is termed as pseudoplastic fluid.
Example- Blood, Paints, etc.
Dilatant Fluid:
Non-Newtonian fluid for which dynamic viscosity increases with an increase in the shear stress is termed as dilatant fluid.
Example- Sugar suspension, Starch suspension, etc.
Rheopectic Fluid:
Fluids for which dynamic viscosity increases with the time are termed as rheopectic fluids.
Example- Gypsum, Bentonite solutions etc.
