Rheology Flashcard

Front

Flocculated suspensions exhibit the flow of a type:

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

Identify the viscometer that is NOT a one point viscometer but can be used for the same purpose: Cup and bob, Falling sphere, Ostwald, Rolling ball.

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