Rheology Quiz

Flocculated suspensions exhibit the flow of a type:

• Dilatant

• Newtonian

• Plastic

• Pseudoplastic

A limitation that is NOT related to the falling sphere viscometer:

• Applicable to only less viscous liquids

• Large volume of sample is required

• Needs the sample to be transparent

• Plug flow

In general, Newtonian fluids are expressed in terms of viscosity. A corresponding expression in non- Newtonian fluids (in terms of viscosity) is:

• Apparent

• Dynamic

• Intrinsic

• Kinematic

One of the following is NOT a one point viscometer but can be used for the same purpose. Pick the viscometer of this type.

• Cup and bob

• Falling sphere

• Ostwald

• Rolling ball

Fluidity is a term associated with Newtonian fluids. An equivalent term in plastic flow fluids is:

• Apparent viscosity

• Flexibility

• Mobility

• Plastic viscosity

Dilatant flow is characterized as a reverse phenomenon of:

• Newtonian flow

• Plastic flow

• Pseudoplastic flow

• Rheopexy

Deflocculated suspension with high concentration of the dispersed solids exhibits the flow of type:

• dilatant

• Newtonian

• plastic

• pseudoplastic

In antithixotropy, the down-curve is frequently positioned to: (with respect to up-curve):

• left

• origin

• right

• superimposable

At equilibrium, the thixotropic behavior of a pseudoplastic system exhibit the state of:

• gel

• paste

• sol

• wax

Which one of the following physical Property is NOT a rheological property?

• body and slip

• spreadability

• surface tension

• viscosity
