Fluid Flow - Medical Science

Q1:

A fluid in which the viscosity decreases with increasing stirrer speed and mixing time, can be represented as

A newtonian fluid

B pseudoplastic, thixotropic fluid

C dilatant, rheopectic fluid

D dilatant, pseudoplastic fluid

ANS:B - pseudoplastic, thixotropic fluid

The fluid shows decreasing in viscosity when increase in shear stress.

Because it is a shear thinning process.

For example : paints and oils.
